Regexp parser: reset flag after scanning ahead for capture groups.
...
When the regexp pattern parser encounters an unbound reference to a
capturing group, it needs to scan ahead to decide whether it really
is a reference. The scan advances to the end of the pattern string
and sets has_more_ to false, but fails to reset it to true so that
later on, parsing a character class wrongly fails.

MIPS: Fix DIRECT_API_CALL_NEW and DIRECT_GETTER_CALL_NEW call.
...
This commit fixes the register usage of DIRECT_API_CALL_NEW
and DIRECT_GETTER_CALL_NEW:
* These functions expect arguments in a0-a1 and not in a1-a2
as the and DIRECT_API_CALL and DIRECT_GETTER_CALL do.
* Fixes the simulator to expect *_NEW arguments in a0-a1.
* Adds more comment to simulator to better explain the
register usage.

idea is to insert a direct call to the miss handler instead of going

directly jump to the runtime.
This cl
1. Cleans up naming
2. localizes the lightweight miss functionality on the only user (compare nil ic)
3. fixes DoCodegen, to actually call the correct method (uninitialized vs initialized)

Make Object.freeze fast

This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty
elements backing stores still end up with slow elements.
Relanding r14758 and r14759 with fix for Test262: only mark properties
and elements READ_ONLY if they are not JS setter/getters. Tightened up
tests to assert frozen-ness, and added targeted tests for the new code
(covering accessors).

Fix Object.freeze on dictionary-backed arrays to properly freeze elements

Follow-up to r14758: slightly rearranges JSObject::Freeze() to avoid duplicating
code while still retaining proper dictionary elements storage behavior.
Also fix a lint error.

This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty
elements backing stores still end up with slow elements.

Refactoring:
* consistent use of SmiTag/Untag
* added a few Smi macros and helpers
Improvements
* small optimisations (e.g. merging untag and cmp #0 )
* added fixed point to double conversion instructions for simpler conversions
More on the last point: a Smi can be seen as a fixed point number with the
a one bit fractional part. Fixed to double instructions allow us to convert
a Smi to a double without untagging.

MIPS: Implement yield* (delegating yield)
...
Port r14669 (b64ce42a)
Original commit message:
Ideally this would have been implemented via desugaring at parse-time,
but yield* is an expression, and its desugaring includes statements like
while and try/catch. We'd have to have BlockExpression in the AST to
support that, and it's not worth it for this feature.
So instead we implement all of the logic in
FullCodeGenerator::VisitYield. Delegating yield AST nodes now have a
try handler index, for the try/catch. Otherwise the implementation is
straightforward.
