commit r14-9564-g994d8f922b9d88f45775f57a490409ab1c3baf59

LoongArch: Combine UNITS_PER_FP_REG and UNITS_PER_FPREG macros.
These macros are completely same in definition, so we can keep the previous
one
and eliminate later one.
gcc/ChangeLog:
* config/loongarch/loongarch.cc
(loongarch_hard_regno_mode_ok_uncached): Combine UNITS_PER_FP_REG
and
UNITS_PER_FPREG macros.
(loongarch_hard_regno_nregs): Ditto.
(loongarch_class_max_nregs): Ditto.
(loongarch_get_separate_components): Ditto.
(loongarch_process_components): Ditto.
* config/loongarch/loongarch.h (UNITS_PER_FPREG): Ditto.
(UNITS_PER_HWFPVALUE): Ditto.
(UNITS_PER_FPVALUE): Ditto.
