LoongArch: Change loongarch_expand_vec_cmp()'s return type from bool to void.

This function is always return true at the end of function implementation,
so the return value is useless.

gcc/ChangeLog:

	* config/loongarch/lasx.md (vec_cmp<mode><mode256_i>): Remove checking
	of loongarch_expand_vec_cmp()'s return value.
	(vec_cmpu<ILASX:mode><mode256_i>): Ditto.
	* config/loongarch/lsx.md (vec_cmp<mode><mode_i>): Ditto.
	(vec_cmpu<ILSX:mode><mode_i>): Ditto.
	* config/loongarch/loongarch-protos.h
	(loongarch_expand_vec_cmp): Change loongarch_expand_vec_cmp()'s return
	type from bool to void.
	* config/loongarch/loongarch.cc (loongarch_expand_vec_cmp): Ditto.
