Don't force target of modulo into a distinct register.
The define_insns for the modulo operation currently force the target register
to a distinct reg in preparation for a possible future peephole combining
div/mod. But this can lead to cases of a needless copy being inserted. Fixed
with the following patch.
gcc/
* config/rs6000/rs6000.md (*mod<mode>3, umod<mode>3): Add
non-earlyclobber alternative.
gcc/testsuite/
* gcc.target/powerpc/mod-no_copy.c: New.
* gcc.target/powerpc/mod-peephole.c: New.
