068c6e5014 Fix a bug in the x64 elements transition code. 
1. The write barrier (RecordWriteStub) expects that pointer stored
points to an initialized object. Specifically, the map must be set
before it is stored.

2. The backing store for smi-only elements can only be reused for
double elements if it is in new-space. Otherwise, we need to allocate
a fresh one because the old one is in pointer-space and the new one
has to be in data-space.

448b620dad Basic interface inference for modules. 
All module expressions, and all variables that might refer to modules,
are assigned interfaces (module types) that are resolved using
unification. This is necessary to deal with the highly recursive
nature of ES6 modules, which does not allow any kind of bottom-up
strategy for resolving module names and paths.

Error messages are rudimental right now. Probably need to track
more information to make them nicer.

1729e3c0dd Make the runtime entry for setting/changing accessors "atomic". 
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.

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

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.
