Move the setting up of callee's callFrame from pushFrame to callToJavaScript thunk
https://bugs.webkit.org/show_bug.cgi?id=123999

Reviewed by Filip Pizlo.

Changed LLInt and/or JIT enabled ports to allocate the stack frame in the
callToJavaScript stub.  Added an additional stub, callToNativeFunction that
allocates a stack frame in a similar way for calling native entry points
that take a single ExecState* argument.  These stubs are implemented
using common macros in LowLevelInterpreter{32_64,64}.asm.  There are also
Windows X86 and X86-64 versions in the corresponding JitStubsXX.h.
The stubs allocate and create a sentinel frame, then create the callee's
frame, populating  the header and arguments from the passed in ProtoCallFrame*.
It is assumed that the caller of either stub does a check for enough stack space
via JSStack::entryCheck().

For ports using the C-Loop interpreter, the prior method for allocating stack
frame and invoking functions is used, namely with JSStack::pushFrame() and
::popFrame().

Made spelling changes "sentinal" -> "sentinel".

[texmap] Borders on rotating images are hidden/wrongly rendered with edge distance antialiasing
https://bugs.webkit.org/show_bug.cgi?id=124653

Patch by José Dapena Paz <jdapena@igalia.com> on 2013-12-04
Reviewed by Noam Rosenthal.

Texture mapper edge distance antialiasing texture sampling was causing
borders to be shaded (and made them almost disappear in some cases).
This was because calculation of sampling happened on vertex shader, so
the border of the texture would go to the border of the inflation area.

What algorithm should do is sampling the border pixel for all the
inflation area (it is the closest pixel to all the samples in
inflation area), and then use the standard sampling for the other
parts of the texture.

No new test because this is already covered by test
transforms/3d/point-mapping/3d-point-mapping.html

* platform/graphics/texmap/TextureMapperShaderProgram.cpp: fix edge
distance antialiasing texture sampling.

Web Inspector: Push Remote Inspector debugging connection management into JavaScriptCore

Reviewed by Timothy Hatcher.

Source/JavaScriptCore:

Move the ENABLE(REMOTE_INSPECTOR) remote debugger connection management
into JavaScriptCore (originally from WebKit/mac). Include enhancements:

  * allow for different types of remote debuggable targets,
    eventually at least a JSContext, WebView, WKView.
  * allow debuggables to be registered and debugged on any thread. Unlike
    WebViews, JSContexts may be run entirely off of the main thread.
  * move the remote connection (XPC connection) itself off of the main thread,
    it doesn't need to be on the main thread.

Make JSContext @class and JavaScriptCore::JSContextRef
"JavaScript" Remote Debuggables.
