8047326 : Consolidate all CompiledIC::CompiledIC implementations and move it to compiledIC.cpp

[Stefan Karlsson]

Hi all,

Currently, we have exactly the same implementation of 
CompiledIC::CompiledIC in all the compiledIC_<arch>.cpp files. I propose 
that we get rid of this code duplication and add just one implementation 
in the compiledIC.cpp file.

This patch is broken out from the G1 Class Unloading code, so I would 
like to push this through the GC repository, if I don't get any objections.
