rs6000: Remove unnecessary option manipulation.
gcc/ChangeLog:
* config/rs6000/rs6000.c (rs6000_override_options_after_change):
Do not set flag_rename_registers, it's already default behavior.
Use EnabledBy for unroll_only_small_loops.
* config/rs6000/rs6000.opt: Use EnabledBy for
unroll_only_small_loops.
