pa.c (emit_move_sequence): Don't copy 0.0 (double precision) directly to memory...
* pa/pa.c (emit_move_sequence): Don't copy 0.0 (double precision)
directly to memory, go through a reg if reload hasn't started.
* pa/pa.md (main movdf pattern): Don't allow 0.0 (double precision)
to be copied directly to memory.
