	* gcc/doc/invoke.texi (-mloongson-mmi): Document.

gcc/testsuite/
	* gcc.target/mips/loongson-shift-count-truncated-1.c
	(dg-options): Run under -mloongson-mmi option.
	Include loongson-mmiintrin.h instead of loongson.h.
	* gcc.target/mips/loongson-simd.c: Likewise.
	* gcc.target/mips/mips.exp (mips_option_groups): Add
	-mloongson-mmi option.
	(mips-dg-options): Add mips_option_dependency options "-mips16" vs
	"-mno-loongson-mmi", "-mmicromips" vs "-mno-loongson-mmi",
	"-msoft-float" vs "-mno-loongson-mmi".
	(mips-dg-init): Add -mloongson-mmi option.
	* lib/target-supports.exp: Rename check_mips_loongson_hw_available
	to check_mips_loongson_mmi_hw_available.
	Rename check_effective_target_mips_loongson_runtime to
	check_effective_target_mips_loongson_mmi_runtime.
	(check_effective_target_vect_int): Use mips_loongson_mmi instead
	of mips_loongson when check et-is-effective-target.
	(add_options_for_mips_loongson_mmi): New proc.
	Rename check_effective_target_mips_loongson to
	check_effective_target_mips_loongson_mmi.
	(check_effective_target_vect_shift,
	check_effective_target_whole_vector_shift,
	check_effective_target_vect_no_int_min_max,
	check_effective_target_vect_no_align,
	check_effective_target_vect_short_mult,
