[PATCH] LoongArch: Modify fp_sp_offset and gp_sp_offset's calculation method, when frame->mask or frame->fmask is zero.

[Lulu Cheng]

gcc/ChangeLog:

        * config/loongarch/loongarch.cc (loongarch_compute_frame_info):
        Modify fp_sp_offset and gp_sp_offset's calculation method,
        when frame->mask or frame->fmask is zero, don't minus UNITS_PER_WORD
        or UNITS_PER_FP_REG.
