rs6000.md (movsi): Don't modify RTL in-place. 

* config/rs6000/rs6000.md (movsi): Don't modify RTL in-place.
(movdi): Make similar to movsi.
* config/rs6000/rs6000.h (ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): There
is no such thing as a DImode CONST_DOUBLE.
* config/rs6000/rs6000.c (output_toc): Likewise.
