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.
