Implement fast literal support in Crankshaft.
...
This extends the current support for nested object literals we already
have in Crankshaft, to also support nested array literals and mixed
nested literals containing arrays and objects. All three types are
generated by the unified HFastLiteral instruction.
All previous upper bounds on nested literal graphs remain unchanged,
keeping the size of generated code in check.
The main intention is to boost performance of two-dimensional array
literals containing constant elements (aka. matrices).

Enable optimization of top-level code and generate deoptimization support lazily.
...
This change enables optimization of top-level and eval-code. For this to work, it adds
support for declaring global variables in optimized code.
At the same time it disables the eager generation of deoptimization support data
in the full code generator (originally introduced in
r10040). This speeds up initial compilation and saves
memory for functions that won't be optimized. It requires
recompiling the function with deoptimization
support when we decide to optimize it.

Ensure that we do a non-incremental GC before relying on weak handle callbacks.
...
Previously, some tests failed when being run with a low GC interval. This was
caused by a switch of the GC to incremental marking mode, which in turn did not
fire any callbacks for weak global handles. Now we make sure that we run in
non-incremental mode, although via a slightly misleading GC flag.
We should probably review the uses of PerformScavenge() and gc() in our tests to
see if they actually mean "make sure our callbacks fired".
