fix some names in compare nil ic

The compare nil ic introduces a mechanism called lightweight miss. The
idea is to insert a direct call to the miss handler instead of going

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)

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.

Preserve optimized code map during GCs weakly.

This change preserves the contents of optimized code maps during GCs but
treats the references in this cache weakly. It uses infrastructure from
code flushing to maintain a list of all caches.

GeneratorFunction() makes generator instances

The current specification has GeneratorFunction() be like Function(),
except that it makes generator instances. This commit implements that

otherwise calling GeneratorFunction or GeneratorFunctionPrototype would
cause an abort because they have no code.
