[ic] Unify CallIC feedback collection and handling.

Consistently collect CallIC feedback in fullcodegen and Ignition, even
for possibly direct eval calls, that were treated specially so far, for
no apparent reason. With the upcoming SharedFunctionInfo based CallIC
feedback, we might be able to even inline certain direct eval calls, if
they manage to hit the eval cache. More importantly, this patch
simplifies the collection and dealing with CallIC feedback (and as a
side effect fixes an inconsistency with feedback for super constructor
calls).
