S390: IC: Eliminate initialization_state as a factor in IC installation.

Browse Source 
Port 56d90782a5

Original commit message:

    In Crankshaft, we would install special ICs that didn't need a vector and slot
    in the MEGAMORPHIC case. This optimization limits our hand against future
    improvements.
