gcc/ChangeLog:
* config/loongarch/loongarch-opts.cc (loongarch_target_option_override):
Delete opts->x_flag_pcc_struct_return.
* config/loongarch/loongarch.h (MAX_FIXED_MODE_SIZE): Set to 64 on LA32.
(DEFAULT_PCC_STRUCT_RETURN): New. If the size of struct <= 2 * GRLEN,
pass by registers if available.
(STACK_BOUNDARY): Set to 128 on LA64 and LA32.
(LARCH_STACK_ALIGN): Set to 16 on LA64 and LA32.
(TRAMPOLINE_SIZE): Set to same value on LA64 and LA32.
