af551bcf6b Don't create rotate instructions in unsupported types, because we don't have
promote/expand code yet.  This fixes the 177.mesa failure on PPC.

a243db8c41 Fix calls that need to store values in stack slots, to not copy the stack
pointer.  This allows us to emit stuff like this:

        li r10, 0

        or r3, r10, r10
        or r4, r10, r10

        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

instead of this:

        or r2, r1, r1     ;; Extraneous copy.
        li r10, 0
        stw r10, 56(r2)
        or r3, r10, r10

3159048c00 Patch #9 from Saem:
"Cut up the runPasses method into smaller pieces.  The small private
helpers should  be easier to deal with when code shuffling arising
from creating the new specialised batchers, not to mention, they're
much easier to understand.

I inlined them, in case function call overhead would be noticeable --
doubtful."
