This adds an additional flag to control whether incremental marking
should be aborted when requesting a GC, providing a finer granularity
between kNoGCFlags and kMakeHeapIterableMask.

Previously, there were 1 or 2 calls to the runtime when accessors were changed
or set. This doesn't really work well with property attributes, leading to some
hacks and complicates things even further when trying to share maps in presence
of accessors. Therefore, the runtime entry now takes the full triple (getter,
setter, attributes), where the getter and/or the setter can be null in case they
shouldn't be changed.

For now, we do basically the same on the native side as we did before on the
JavaScript side, but this will change in future CLs, the current CL is already
large enough.

Note that object literals with a getter and a setter for the same property still
do 2 calls, but this is a little bit more tricky to fix and will be handled in a
separate CL.

This allows the test harness to download missing test suite data if
necessary. We use the bzip2 archive for test262 because it is faster
than cloning the repository and also works without any Mercurial
installation.

Instead of creating a fresh basic block for the inlined body,
I just simulate the outer environment in the middle of the current
block before updating the current environment to the inlined environment and
emitting the enter-inlined instruction.

The heap profiler randomly crashed because of memory corruption caused
by unexpected heap objects layout changes occured between count and fill
passes. The changes lead the number of retainers counted on the first pass
did not match its number on the fill pass leading to the out of bounds
array access.

Besides that the mark bit scheme has been changed to a plain vector one in
dominators building algorithm. It is up to 4x faster because of smaller
memory access footprint.

Inlined strict mode functions (that are not called as methods) will get
their receiver reset to undefined. This should not happen when inlining
constructors.

This change also simplifies the test suite to reuse the same closures
into which constructors get inlined and use gc() to force V8 to forget
collected type feedback.

This is essential for the upcoming map sharing with accessors, and we aleady
have enough machinery to handle the holes now. Furthermore, use "To" template in
2 nearby functions, and made naming a bit more consistent.

In a nutshell: This CL should have no visible effect at all at the moment.
