gcc/ChangeLog:
* config/loongarch/genopts/loongarch.opt.in: Mark -m[no-]recip as
aliases to -mrecip={all,none}.
* config/loongarch/loongarch.opt: Same.
* config/loongarch/loongarch-def.h: Modify ABI condition macros for
convenience.
* config/loongarch/loongarch-opts.cc: Define option-handling
procedures split from the original loongarch_option_override_internal.
* config/loongarch/loongarch-opts.h: Same.
* config/loongarch/loongarch.cc: Clean up
loongarch_option_override_internal.
