(move_to_float insns): Change move_to_float so that it doesn't have a
clobber of the memory address, and instead passes the stack temp's
memory address as one of the unspec args.
(fix_truncdfsi2): Use rs6000_stack_temp to allocate the temp.
(multiply, shift insns): Fix all cases of multiply and shift insns so
that the right mnemonics are used for -mcpu=common with both
-m{old,new}-mnemonics.
