77079b6fd3 Avoid sharing AccessorPairs during Genesis. 
To test the upcoming changes for map sharing in the presence of accessors, it is
essential that we keep a few global invariants: The map tree should always stay
a tree and AccessorPairs should not be shared between different DescriptorArrays
and/or StringDictionaries. This CL adds a test method for the latter invariant
and makes some changes to the bootstrapping process to avoid such sharing.

Note that we can't enable the new test method permanently yet, because we
currently go back and forth between fast mode and slow mode when adding an
accessor and break this invariant temporarily. This will be handled in a
separate CL.

f06b182f8e Moved access checks out of Dictionary class. 
The checks were at the wrong abstraction level, JSObject is the right place for
this check. Note that other uses of ValueAtPut either don't need a check at all
(like the one used for copying boilerplate) or do the check for themselves.

1dd2b094a5 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).

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.
