Implement graph trimming in ControlReducer.
...
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.
This CL is one half of the ControlReducer functionality, the other half
being branch folding.

"Throughout the rest of this document, the phrase “code unit” and the
word “character” will be used to refer to a 16-bit unsigned value
used to represent a single 16-bit unit of text."
This changed in ES6 draft section 10.1 ("Source Text"):
"The ECMAScript code is expressed using Unicode, version 5.1 or later.
ECMAScript source text is a sequence of code points. All Unicode code
point values from U+0000 to U+10FFFF, including surrogate code points,
may occur in source text where permitted by the ECMAScript grammars."

Move state sentinels into TypeFeedbackVector.
...
These sentinels were in the wrong place, living in only tangentially related class TypeFeedbackInfo, but they codify state in the TypeFeedbackVector.

Introduce TypeFeedbackVector, as FixedArray grew constrictive.
...
The TypeFeedbackVector is poised to host significant functionality. While it
remains a FixedArray under the covers, we need a place to hold logic and
definitions unique to its function.

Removing ic.h from code-stubs.h
...
CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.
More work could/should be done here, but this is a first step.
