Tiled layers are missing content on zooming
https://bugs.webkit.org/show_bug.cgi?id=100422

Reviewed by Beth Dakin.

Source/WebCore:

Tiled layers using TileCaches were missing content after
zooming. TileCache was confused in the presence of scaling;
it unapplies the scale on the layer above the tiles (so the tiles
live in screen space), and computed the tile coverage rect
in these tile coordinates. This worked for the page tile cache,
because its visibleRect was sent in pre-scaled. However, for
tiled layer TileCaches this was wrong.

Fix by scaling the tile coverage rect by m_scale before
using it to compute which tiles to throw away and bring in.

To fix the problem of the visibleRect being pre-scaled
for the page tile cache, remove the setting of the visibleRect
in RenderLayerCompositor::frameViewDidScroll(), and rely on
GraphicsLayerCA::updateVisibleRect() which computes the
visible rect in the correct, layer coordinates.

Test: compositing/tiling/tile-cache-zoomed.html

* platform/graphics/ca/GraphicsLayerCA.cpp:
(WebCore::GraphicsLayerCA::updateVisibleRect): Call setVisibleRect()
for all tile cache layers, not just tiled layer ones, but only do
the visible rect adjustment for those that are not the page tile cache.
* platform/graphics/ca/mac/TileCache.mm:
(WebCore::TileCache::revalidateTiles): Use a coverageRectInTileCoords rect,
which is scaled to be in the same coordinate space as the tile grid.
* rendering/RenderLayerCompositor.cpp:
(WebCore::RenderLayerCompositor::frameViewDidScroll): Remove the code
that sets the setVisibleRect() on the TiledBacking.

LayoutTests:

New test for zooming with a tiled layer, and adjust an existing result.

REGRESSION (132422): Tiles don't move when the Find dialog causes programmatic scrolls
https://bugs.webkit.org/show_bug.cgi?id=100433
<rdar://problem/12575582>

Reviewed by Simon Fraser.

Actually update GraphicsLayer positions from updateMainFrameScrollPosition if
we're doing a programmatic scroll; otherwise programmatic scrolls while scrolling
on the main thread will short-circuit and end up only updating the GraphicsLayer's
notion of its current position, but never synchronizing that to the layer itself.

No new tests, as this is currently untestable.

Turn PageLoad tests into simple performancetests, commit #4 
https://bugs.webkit.org/show_bug.cgi?id=99899

Reviewed by Ryosuke Niwa.

We cannot provide an elegant way to measure the memory consumption of the PageLoad tests, but we can turn them into simple
performance tests and measure their memory footprint and performance that way. This change moves and renames the related files
to their new location and adds html/js wrappers for them.

This is the #4 commit of the whole patch.
