Rename soft-fp op-[1248].h variables to avoid risk of shadowing.

Continuing the soft-fp variable renaming from
<https://sourceware.org/ml/libc-alpha/2014-06/msg00434.html> to avoid
shadowing if two macros happen to use the same variable name and that
variable is involved in an argument one of those macros passes to
another, this patch renames variables in op-[1248].h.  (The two
patches are to different files and are independent of each other.)

Tested for powerpc32 (soft-float) and mips64 that this makes no change
to the disassembly of installed shared libraries.
