rx: Cleanup non-VOIDmode SETs. 

SET should always have VOIDmode.  A number of places used
SImode or QImode for the mode of the SET rtx itself.

2011-01-17 Richard Henderson <rth@redhat.com>
* config/rx/rx.c (gen_rx_store_vector): Use VOIDmode for gen_rtx_SET.
(gen_rx_rtsd_vector, gen_rx_popm_vector): Likewise.
* config/rx/rx.md (pop_and_return): Use VOIDmode for SET.
(stack_push, stack_pushm, stack_pop, stack_popm): Likewise.
(bitset, bitset_in_memory): Likewise.
(bitinvert, bitinvert_in_memory): Likewise.
(bitclr, bitclr_in_memory): Likewise.
(insv, sync_lock_test_and_setsi, movstr, rx_movstr): Likewise.
(rx_strend, rx_cmpstrn): Likewise.
(rx_setmem): Likewise. Make the source BLKmode to match the dest.
(bitop peep2 patterns): Remove.
* config/rx/rx.c (rx_match_ccmode): New.
* config/rx/rx-protos.h: Update.
* config/rx/rx.md (abssi2): Clobber, don't set flags.
