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.

We go back to patching the code for lazy deoptimization because ICs need the on-stack return address to read/update the IC address/state.
The change also fixes bunch of tests, mostly by adding more deoptimization points.
(We still need to add code to ensure lazy deopt patching does not overwrite ICs and other lazy deopts; this is coming next.)

Fix deoptimization address patching in Turbofan to use safepoints.
...
Since the deopt patch address needs to be available during GC to
resolve safepoints, we need to move it to the code object (instead of
the deoptimization input data) - accessing a separate fixed array
is not safe during GC. This CL adds a deoptimization_pc field to
each safepoint. The fields points to the deoptimization block.
The CL also fixes wrong register allocator constraints for
frame states on calls. These should always live on the stack
because registers are not preserved during a call.
