The TypeFeedbackVector is poised to host significant functionality. While it
remains a FixedArray under the covers, we need a place to hold logic and

This is a purely mechanical refactoring and a first step towards being
able to report more helpful deoptimization reasons. With this
refactoring, we know at least the mnemonic of the instruction causing
the deopt, although this is not used yet. Future steps will be using
the mnemonic, passing additional explicit deopt reasons and removing
the fragile machinery of searching for code comments.

Every DeoptimizeIf should be preceded by a RecordComment explaining
the reason. In the long run, the reason should be an argument of
DeoptimizeIf, but we're not there yet.

On x87, things are a bit ugly due to some pushing/popping, so if
somebody feels inclined to improve this: Feel free. Probably the right
approach would be reloading instead of the push/pop horror.

Another thing is our inconsistent handling of the "done" continuation
of deferred code on the various platforms, I made tiny changes on the
way, but this should better be unified somehow, with all those
micro-optimizations removed.

original commit message:

  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.
