Fix handling of flag_rename_registers by a target.
PR target/102688
gcc/ChangeLog:
* common.opt: Use EnabledBy instead of detection in
finish_options and process_options.
* opts.c (finish_options): Remove handling of
x_flag_unroll_all_loops.
* toplev.c (process_options): Likewise for flag_web and
flag_rename_registers.
