* emit-rtl.c (set_mem_size): New function.
* expr.h (set_mem_size): Declare.
* config/rs6000/rs6000.c (expand_block_move_mem): Exterminate.
(expand_block_move): Instead, use adjust_address and
replace_equiv_address to generate proper aliasing info.
Move common code out of conditionals. Localize vars.
