X87: Removing ic.h from code-stubs.h

port r23977.

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.
