Give ADJCALLSTACKDOWN/UP the correct operands.

Give a whole bunch of other stuff variable operands, particularly FP. The
FP stackifier is playing fast and loose with operands here, so we have to
mark them all as variable. This will have to be fixed before we can dag->dag
the X86 backend. The solution is for the pre-stackifier and post-stackifier
instructions to all be disjoint.
