This is a temporary workaround for the fact that a good deal of the code that triggers access checks, which in turn externalize strings, is not yet handlified and therefore not GC safe.

for the PropertyCallbackInfo and FunctionCallbackInfo fields. Also, the indices

ECMA262 5.1th, v8::Function::Call and Object::CallAsFunction should take

Use a walking visitor to traverse JSObject structure. The purpose is to prepare for more complex context-dependent walks of the structure, needed for allocation site and pretenuring work. Different visitors can be created that annotate the object in various ways.

Re-land "Add methods to enable configuration of ResourceConstraints based on limits derived at runtime."

Adds ConfigureResourceConstraintsForCurrentPlatform and SetDefaultResourceConstraintsForCurrentPlatform which configure the heap based on the available physical memory, rather than hard-coding by platform as previous. This change also adds OS::TotalPhysicalMemory to platform.h.

The re-land fix the performance regression caused by accidental change in default max young space size.
