2f1f203bff Fix pc to code cache so it can cope with a pointer to the start of the code 
object.  Rename it to be the inner pointer to code cache.

22ef98dc66 Fix a deoptimization bug. 
We reset the count of outgoing arguments, used for the index in the
frame's outgoing arguments, for each level of inlining.  This could
result in the arguments overlapping, rather than stacking on top of
each other.

cf63503cad Unify the handling of comparinsons against null and undefined. 
Although this patch is not small, most parts of it are rather mechanical:

 * First of all, the concept of a 'nil-like' value is introduced, which can be
   null or undefined. They are treated symmetrically regarding comparisons, so
   it makes sense to handle them in a uniform manner. It is a mystery why
   JavaScript defines two of those beasts, when even *one* is a design wart...

 * Extended and renamed a few things which now handle undefined in addition to
   null.

 * Made the parts of the full code generator and the hydrogen generation which
   deal with comparisons a bit more similar regarding their handling of special
   cases.

 * Refactored the syntactical detection of special cases for comparisons,
   hopefully making them a bit more readable and less copy-n-paste-oriented.
   Things like this should really be a one-liner in any sane programming
   language... :-P

 * Cut down the length of the argument lists of a few functions to something
   less insane, making them more easily understandable locally. This involves
   minor code duplication, but this was a good tradeoff and can be remedied
   later if necessary.

 * Replaced some boolean arguments with more readable enums.

 * Fixed a TODO: Values which are definitely a Smi or unboxed can never be equal
   to null or undefined.

433db37747 MIPS: port Implement function proxies (except for their use as constructors). 
port r9258 (c8709a9)

Note on mips implementation: Arm reg r4 (call type) normally maps to mips
reg t0. We had already used t0 as a temp in Generate_FunctionCall() and
Generate_FunctionApply(), so I replaced that existing t0 usage with t3, and
now use t0 only for call type.

Original commit message:
Introduce new %Apply native.
Extend Execution::Call to optionally handle receiver rewriting (needed for %Apply).
Fix Function.prototype.bind for functions that have .apply modified.

c74aae242a MIPS: pre-crankshaft updates to code-stubs and stub-cache (3/3) 
Highlights:
- code-stubs-mips.cc
-- use EmitFPUTruncate in place of inline code in several places.
-- use BranchF macro rather than lower-level FP cmp and branch for readability.
-- Port of Sven's r8859 (Implement type recording for ToBoolean) and r8886
(Simplify and optimize ToBoolean handling.)
-- Fix bug in TranscendentalCacheStub::Generate where some regs were not
saved across CFunction call.
-- use updated xxxCFunction macros.
-- update InstanceOfStub to support crankshaft
DoDeferredLInstanceOfKnownGlobal
-- Provide code-patching and I-cache flushing support for generated
code, used for InstanceOfStub under crankshaft (not submitted here).
This requires adding new ExternalReference to src/assember.cc,h

- stub-cache-mips.cc
-- port Danno's r8901 (Create a common base class for Fixed-, FixedDouble-
and ExternalArrays) to mips crankshaft branch.

8c744768e2 Nuke CompareToNull AST node. 
The Great Master Plan is to move the recognition of special cases for
comparisons further down the compilation pipeline where more information is
available. This is a first step into this direction: The special handling of
equality comparisons involving null is pushed from the parser to the code
generators, removing the need for a special AST node. (There are rumors from
usually well-informed sources that this node type is actually a relic of ancient
crankshaft days...)

The next steps will be the unification of null/undefined handling and pushing
the special case handling in crankshaft even further down the pipeline, enabling
the recognition of cases like "var foo=null; if (foo === bar) ...", but these
will be in separate CLs.
