X87: VectorICs: refactoring to eliminate "for queries only" vector ic mode.

X87: VectorICs: refactoring to eliminate "for queries only" vector ic mode.

port 1a5751f9b3ca682fadb6fce8202dda2db5b017c6 (r29956)

original commit message:

    Since we need the notion of a dummy vector ic, we can use that to avoid
    a special case of the IC constructor. Also, consolidate the two dummy
    ICs into one.
