3b445f14f8 X64 tweaks. 
Use movapd instead of movsd to move between xmm registers. Avoids partial
register writes and potential stalls.

Use xorps instead of xorpd to zero a register. Same effect and latency, but
one byte smaller.

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.

dab8f48ebc ARM: Implement correct rounding in the lithium codegenerator. 
This patch provides testing for values that have a fraction part of 0.5 and uses a different rounding method for them. The original method of VFPTruncating the value with round-to-nearest is not correct because it does not round to the larger number in case of a tie.

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)

The type recording binary operations stub contained a number of issues which broke V8 when running without VFPv3 supoort.

2. Missing allocation of a heap number for the result
3. Missing call to runtime

4618b186ef Change the list of statements that are inlineable into a black-list. 
Before we had a white-list of things that we allow inside inlined functions.

This way we can enable new constructs one-by-one.

a932441a0c Cleanup of ScannerConstants, now named UnicodeCache. 
The ScannerConstants class was originally static fields on the scanner class.
During creation of the stand-alone preparser and later isolates, it has been
moved into a separate class with a per-isolate instance.
It is used to hold caching unicode Predicate values.

This change renames the class to UnicodeCache, and passes a reference
to the instance down to methods that doesn't have an easy access to
an isolate (to avoid, e.g., having to do an Isolate::Current() for every
number parsed).
