6b5a4cdef2 V8 Microtask Queue & API
This patch generalizes Object.observe callbacks and promise resolution into a FIFO queue called a "microtask queue".

It also exposes new V8 API which exposes the microtask queue to the embedder. In particular, it allows the embedder to

-schedule a microtask (EnqueueExternalMicrotask)
-run the microtask queue (RunMicrotasks)
-control whether the microtask queue is run automatically within V8 when the last script exits (SetAutorunMicrotasks).

51107bad1c Skip webkit/function-apply-aliased.js when running on simulators.
The webkit/function-apply-aliased.js test fails on simulators (both MIPS
and ARM) as the printed output does not match to the expected. The
failing test forces a stack overflow exception and the ToString()
operation of the exception object fails because of an other stack
overflow and returns an empty string.

The problem is that on hardware a common JS and C stack is used so the
stack overflow can be caught in C functions also while on simulator
separated JS and C stacks are used.

This patch adds a "sim" condition to test .status files to skip tests
only on simulator.

b25bb230cd Removed apiutils.h and related cleanup.
ExtensionConfiguration is just a simple container for extension names
(in a perfect world we would use vector<string> and range-based for
loops), and HandleScopeData was in the totally wrong place. Some
additional cleanup on the way, e.g. using the null pattern behind our
external API.

2638dca48f Make cells pointing to JSObjects weak in optimized code.
This is done similar to weak embedded objects in optimized code (r17102). The
reference from optimized code to a cell is treated weakly in marking visitors
if the cell points to a JSObject. After marking we iterate over all cells
embedded in optimized code. If a cell is not marked but its value is marked,
then we revive the cell by marking it. Otherwise, the cell value is dead, so
we mark the code for deoptimization.
