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

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.

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.

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.

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)

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.

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.
