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.

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.

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.

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.
