4d1b2b1d38 Change the Hydrogen representation of uses. 
Rather than representing a use as a pointer to an HValue and then searching
for the specific (ambiguous) operand, we now represent a use as a pair of an
HValue and the input operand index.  Additionally, use a linked list instead
of a growable array list since we never use random access.

This allows us to remove a bunch of similarly named and subtly different
functions from the HValue API.  The cost in extra zone allocation per use is
partially offset by reusing use list nodes when replacing a use of one value
with another.

6b7a4f154d Reduce the number of virtual function in hydrogen-instruction.h classes 
Instead of using virtual type-tester functions we can just
generate non-virtual ones for all concrete IR classes.

This is changes reduces the V8 binary size by ~2%.

I also simplified the macros to declare new hydrogen instructions slightly.
The name used for debug output is no longer passed as a separate string.
Instead we just use the class name.

7aec228dbb Cleanup of mjsunit.js code and make assertEquals more strict. 
Encapsulate the helper functions in mjsunit.js.
Now only exposes the exception class and the assertXXX functions.

Make assertEquals use === instead of ==.
This prevents a lot of possiblefalse positives in tests, and avoids
having to do assertTrue(expected === actual) when you need it.

Fixed some tests that were either buggy or assuming == test.

8aaa0c6b18 Add v8Locale.Collator 
This is a partial implementation of Collator per what's agreed upon at the last
ECMAScript meeting + mailing list. Only the following three options are implemented: ignoreAccent, ignoreCase, numeric. 

ChromeOS and Chrome need this feature for M12. This could be added as chrome extension API. Giiven that we have a rough agreement on the collation part of ECMAScript API, we thought it'd save us some duplicated work adding this to v8 (experimental i18n api) now rather than implementing it in Chrome now and moving it later.

418501faef Refine allocation policy for input operands at calls. 
For instructions that are marked as calls we can use:

1. Fixed input registers

2. Use-at-start policy (register, memory or constant).

(Memory or constant would not need the use-at-start policy, but
not specifying use-at-start prevents the allocator from using
a register even if there is one available. That's why use-at-start
is required and guarded by assertion)

db91b43ace Fix a just-introduced bug in polymorphic inlining. 
When inlining a polymorphic variant, the inlined function indicates we
should bailout of the entire compilation by setting the stack overflow flag
on the visitor.  We need to check this flag and bailout if a call to
TryInline succeeds and it is not in tail position in a graph builder
function.

6b12b41f30 ARM: Fix a number of issues with running without VFPv3 support 
The type recording binary operations stub contained a number of issues which broke V8 when running without VFPv3 supoort.

1. The order of the high/low words of doubles in core register pairs where wrong
2. Missing allocation of a heap number for the result
3. Missing call to runtime

Added the option for printing the double values in register pairs to the simulator.

c25c2784d9 Relax assumptions about control flow in the hydrogen graph. 
Previously we assumed that control was always live after visiting an
expression, and that control was live to both basic block targets of an
expression in a test context.

Now we allow any expression to exit the graph.
