Object allocation sinking should have a sound story for picking materialization points
https://bugs.webkit.org/show_bug.cgi?id=137315

Reviewed by Oliver Hunt.
        
The only missing piece was having the object allocation sinking phase locate materialization
points that were at CFG edges.
        
The logic for how and why this "just works" relies on some properties of critical edge
breaking, so I was fairly careful in how I did this. Also, this requires inserting things at
the "first origin node" of a block - that is the first node in a block that has a NodeOrigin
and therefore is allowed to exit. We basically had support for such a notion before, but
didn't close the loop on it; this patch does that.
        
Also I added the ability to provide a BasicBlock* as context for a DFG_ASSERT().

Have is<>(T*) function do a null check on the pointer argument
https://bugs.webkit.org/show_bug.cgi?id=137333

Reviewed by Gavin Barraclough.

Have is<>(T*) function do a null check on the argument instead of a
simple assertion. This makes sense for 2 reasons:
1. It is more consistent with downcast<>(T*), which will succeed even
   if the argument is a nullptr.
2. It simplifies the code a bit as it gets rid of a lot of explicit
   null checks.

Do all closed variable access through the local lexical object
https://bugs.webkit.org/show_bug.cgi?id=136869

Reviewed by Filip Pizlo.

This patch makes all reads and writes from captured registers
go through the lexical record, and by doing so removes the
need for record tearoff.

To keep the patch simple we still number variables as though
they are local stack allocated registers, but ::local() will
fail. When local fails we perform a generic resolve, and in
that resolve we now use a ResolveScopeInfo struct to pass
around information about whether a lookup is a statically
known captured variable, and its location in the activation.
To ensure correct behaviour during codeblock linking we also
add a LocalClosureVariable resolution type.

To ensure correct semantics for the Arguments object, we now
have to eagerly create the Arguments object for any function
that uses both the Arguments object and requires a lexical
record.

Back TextRun with a StringView
https://bugs.webkit.org/show_bug.cgi?id=137352

Reviewed by Antti Koivisto.

TextRun contains a union of a UChar* and an LChar* as well as a length, which is the abstraction
that StringView is intended to be. This patch cleans up TextRun by replacing the union and length
with a StringView instance member.

No new tests because there is no behavior change.

WKDownloadCopyRequest() returns 0 until the download starts
https://bugs.webkit.org/show_bug.cgi?id=137322

Reviewed by Anders Carlsson.

The m_request ivar in DownloadProxy was only being initialized when didStart() was called after the

(WebCore::FrameView::wheelEvent):
Inform PageOverlayController that something scrolled.

(WebCore::FrameView::setExposedRect):
Inform PageOverlayController that the exposed rect changed, so it can push
the new exposed rect down to the overlays.

* page/FrameView.h:
Add didChangeScrollOffset.

* page/MainFrame.cpp:
(WebCore::MainFrame::MainFrame):
* page/MainFrame.h:
Keep one PageOverlayController per MainFrame.

* page/Page.cpp:
(WebCore::Page::setDeviceScaleFactor):
Inform PageOverlayController that the device scale factor changed.

(WebCore::Page::setSessionID):
Remove a blank line.

* page/PageOverlay.cpp: Renamed from Source/WebKit2/WebProcess/WebPage/PageOverlay.cpp.
Move PageOverlay from WebKit2 to WebCore.
A few overarching changes that I won't detail in each place:
    - references instead of pointers in many places
    - WebCore types instead of WebKit2 types everywhere

(WebCore::PageOverlay::bounds):
It is possible to install an overlay before we have a FrameView.
We will eventually get a view/contents size changed notification and try again.

(WebCore::PageOverlay::copyAccessibilityAttributeStringValueForPoint):
(WebCore::PageOverlay::copyAccessibilityAttributeBoolValueForPoint):
(WebCore::PageOverlay::copyAccessibilityAttributeNames):
Split copyAccessibilityAttribute into "StringValueForPoint" and "BoolValueForPoint"
variants, because we don't have anything like WKTypeRef here.

* page/PageOverlay.h: Renamed from Source/WebKit2/WebProcess/WebPage/PageOverlay.h.
Make PageOverlay a normal RefCounted object instead of a WebKit2 API object.
Leave a comment noting that we should move the PageOverlay's GraphicsLayer
to PageOverlay instead of a map on PageOverlayController.

* page/PageOverlayController.cpp: Renamed from Source/WebKit2/WebProcess/WebPage/PageOverlayController.cpp.
Move PageOverlayController from WebKit2 to WebCore.
A few overarching changes that I won't detail in each place:
    - references instead of pointers in many places
    - WebCore types instead of WebKit2 types everywhere

Leave a FIXME that didChangeSettings is not currently called when settings change.
This is not a problem for normal use of overlays, only for dynamically changing
layer border/repaint counter settings.

(WebCore::PageOverlayController::PageOverlayController):
(WebCore::PageOverlayController::createRootLayersIfNeeded):
We will now lazily initialize the root layers when we first try to use them,
because otherwise we try to create them before the ChromeClient's GraphicsLayerFactory
is hooked up, in some cases, and that can cause us to create the wrong kind of GraphicsLayers.

(WebCore::PageOverlayController::installPageOverlay):
Enter compositing mode when installing a PageOverlay.
Avoid pushing the Page to the PageOverlay until after we've set up
its root layer, so that the installation process can make use of that layer;
clients may, for example, expect to be able to setNeedsDisplay() in the
didMoveToPage callback.
Avoid updateOverlayGeometry until the layer is created and we've pushed
the Page down, so that e.g. bounds() will use the right Page.

(WebCore::PageOverlayController::didChangeSettings):
Leave a FIXME about a future improvement to didChangeSettings.

(WebCore::PageOverlayController::deviceScaleFactor):
(WebCore::PageOverlayController::notifyFlushRequired):
Null-check Page; these can get called when tearing down the Frame.

* page/PageOverlayController.h: Renamed from Source/WebKit2/WebProcess/WebPage/PageOverlayController.h.

* platform/graphics/GraphicsLayerClient.h:
Add wtf/Forward.h, because GraphicsLayerClient.h uses String.

* rendering/RenderLayer.cpp:
(WebCore::RenderLayer::scrollTo):
Inform PageOverlayController that something scrolled.

* rendering/RenderLayerCompositor.cpp:
(WebCore::RenderLayerCompositor::hasAnyAdditionalCompositedLayers):
Make hasAnyAdditionalCompositedLayers return true if there are any page overlays,
because we need to avoid falling out of compositing mode if we still have
page overlays.

(WebCore::RenderLayerCompositor::updateCompositingLayers):
Enter compositing mode if we have page overlays.

(WebCore::RenderLayerCompositor::appendOverlayLayers): Deleted.
(WebCore::RenderLayerCompositor::appendDocumentOverlayLayers):
Rename appendOverlayLayers -> appendDocumentOverlayLayers.

(WebCore::RenderLayerCompositor::attachRootLayer):
(WebCore::RenderLayerCompositor::detachRootLayer):
Attach/detach the view overlay root layer when attaching/detaching the
normal compositing root layer.

(WebCore::RenderLayerCompositor::rootLayerAttachmentChanged):
* rendering/RenderLayerCompositor.h:

* CMakeLists.txt:
* WebKit2.xcodeproj/project.pbxproj:
Make the appropriate build system changes.

* WebProcess/InjectedBundle/API/c/WKBundleAPICast.h:
Make WKBundlePageOverlayRef map to WebPageOverlay instead of PageOverlay.

* WebProcess/InjectedBundle/API/c/WKBundlePage.cpp:
(WKBundlePageInstallPageOverlay):
(WKBundlePageUninstallPageOverlay):
(WKBundlePageInstallPageOverlayWithAnimation):
(WKBundlePageUninstallPageOverlayWithAnimation):
Forward PageOverlay installation/uninstallation to WebCore.

* WebProcess/InjectedBundle/API/c/WKBundlePageOverlay.cpp:
(WKBundlePageOverlayGetTypeID):
(WKBundlePageOverlayCreate):
(WKBundlePageOverlaySetAccessibilityClient):
Use WebPageOverlay instead of PageOverlay, and references instead of pointers.
We forward client callbacks through from PageOverlay::Client to WebPageOverlay::Client.

(PageOverlayClientImpl::copyAccessibilityAttributeValue):
(PageOverlayClientImpl::copyAccessibilityAttributeNames):
Convert from wtf types to WebKit2 types.

* WebProcess/WebCoreSupport/WebChromeClient.cpp:
(WebKit::WebChromeClient::graphicsLayerFactory):
If we don't have a drawing area, don't dereference it!

(WebKit::WebChromeClient::attachViewOverlayGraphicsLayer):
Forward attachViewOverlayGraphicsLayer to the DrawingArea.

* WebProcess/WebCoreSupport/WebChromeClient.h:

* WebProcess/WebCoreSupport/WebInspectorClient.cpp:
* WebProcess/WebCoreSupport/WebInspectorClient.h:
* WebProcess/WebPage/FindController.cpp:

* WebProcess/WebPage/ios/FindIndicatorOverlayClientIOS.h:
* WebProcess/WebPage/mac/ServicesOverlayController.mm:
* WebProcess/WebPage/ServicesOverlayController.h:
Mechanical changes to adopt to the fact that PageOverlay is in WebCore now.

* WebProcess/WebPage/LayerTreeHost.h:
* WebProcess/WebPage/WebPage.cpp:
* WebProcess/WebPage/WebPage.h:
Remove support for WebKit2-based page overlays.
Return MainFrame instead of Frame from mainFrame().

WebPageOverlay exists to be our API object, but forwards everything
to its WebCore::PageOverlay, and implements WebCore::PageOverlay::Client, and
forwards client callbacks to its WebPageOverlay::Client (which
WKBundlePageOverlay implements).

* WebProcess/WebPage/mac/WKAccessibilityWebPageObjectMac.mm:
(-[WKAccessibilityWebPageObject accessibilityParameterizedAttributeNames]):
(-[WKAccessibilityWebPageObject accessibilityAttributeValue:forParameter:]):
