596a0fa73c MIPS: Re-worked the deopt entry table. 
This method works around the Branch offset and relocinfo issues by emulating a pc-relative jump.
This allows us to generate larger entry tables. The theoretical limit is 2^16 (number of entries)
but even that can be extended by allowing a larger instruction count.

Also reverted the mips-specific constant (kNumberOfEntries) in deoptimizer.h

bd79e299e5 Uniformly handle 'undefined' store to Float64Array and Float32Array. 
Previous behavior diverged in ICs and Crankshaft. When storing to a Float32Array or Float64Array, the ICs treated undefined as zero while Crankshaft treated it as NaN. Now both ICs and Crankshaft treat it as NaN, which is consistent with the WebGL & ECMAScript spec.

0be449d684 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.

8a7f1568c4 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".
