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
through the deopt routine. This can be use for uninitialized stubs, to
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).

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.

The current specification has GeneratorFunction() be like Function(),
except that it makes generator instances. This commit implements that
behavior. It also fills in a piece of the implementation where
otherwise calling GeneratorFunction or GeneratorFunctionPrototype would

Skip samples where top function's stack frame is not setup properly
...
Stack iterator takes return address based on the frame pointer (ebp) and detects JS frames based on value at fp + StandardFrameConstants::kMarkerOffset. So in order the iterator to work correctly this values should be already setup for the current function. Stack frame is constructed at the very beginning of JS function code and destroyed before return. If sample is taken before before the frame construction is completed or after it was destroyed the stack iterator will wrongly think that FP points at the current functions frame base and will skip callers frame. To avoid this we mark code ranges where stack frame doesn't exist and completely ignore such samples.
This fixes cctest/test-cpu-profiler/CollectCpuProfile flakiness.

Implement yield* (delegating yield)

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.

Casting NaN to int is unpredictable, on different architectures it produces different int value.

Remove separate maps for function instances
...
ES3 specified that functions created via Function() would have
enumerable prototypes, unlike function literals. For this reason, V8
has always had two prototypes for functions: "function_map" for
literals, and "function_instance_map" for "function instances": those
functions created by Function().
However, since 2009 or so, both maps have been the same! Both have had
writable, non-enumerable prototypes. Moreover, ES5 changed to specify
that function instances would have non-enumerable prototypes.
This patch removes the separate maps for function instances in sloppy
and strict mode.

Cleaned up Crankshaft pipeline a bit.
...
Two tiny changes:
* Some phases were missing an HPhase, which was added, so we can now see all
phases in the visualizer output.
* Consistently test commandline flags directly in the pipeline, making it
clearer which parts are optional and which are not.
