Instance-type-related fixes and cleanup.
...
Things got quite a bit out of sync (don't we all love copy-n-paste?):
* TypeToString didn't handle SLICED_STRING_TYPE,
SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE,
JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE.
* INSTANCE_TYPE_LIST was missing entries for
SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE.
To improve this maintenance nightmare a little bit, the missing
instance types were added to the INSTANCE_TYPE_LIST macro and this
list is now used via our beloved 2nd order macro technique in
TypeToString. As a side-effect, the strings returned by TypeToString
have a "_TYPE" suffix now, but this doesn't really matter and is a
small price to pay for consistency.
Removed INVALID_TYPE on the way, it had no real use.

This patch defines one PositionBits field for LInstruction and copies the

MIPS: First implementation of allocation elimination in Hydrogen.
...
Port r16098 (328ff5f7)
Original commit message:
This change implements a simple data-flow analysis pass over captured
objects to the existing escape analysis. It tracks the state of values
in the Hydrogen graph through CapturedObject marker instructions that
are used to construct an appropriate translation for the deoptimizer to
be able to materialize these objects again.
This can be considered a combination of scalar replacement of loads and
stores on captured objects and sinking of unused allocations.
