Exec mask manipulation inserted by SIWholeQuadMode barriers to
instruction scheduling.  Move the entire pass after the machine
instruction scheduler and make changes so pass is correct for
non-SSA operation.  These changes should leave the pass still
usable pre-scheduler, although tests have be updated to reflect
post-scheduler results.
