Log:
Add support for Loongson MMI instructions.

gcc/
	* config.gcc (extra_headers): Add loongson-mmiintrin.h.
	* config/mips/loongson.md: Move to ...
	* config/mips/loongson-mmi.md: here; Adjustment.
	* config/mips/loongson.h: Move to ...
	State as deprecated. Include loongson-mmiintrin.h for back
	compatibility and warning.
	* config/mips/loongson-mmiintrin.h: ... here.
	* config/mips/mips.c (mips_hard_regno_mode_ok_uncached,
	mips_vector_mode_supported_p, AVAIL_NON_MIPS16): Use
	TARGET_LOONGSON_MMI instead of TARGET_LOONGSON_VECTORS.
	(mips_option_override): Make sure MMI use hard float;
	(mips_shift_truncation_mask, mips_expand_vpc_loongson_even_odd,
	mips_expand_vpc_loongson_pshufh, mips_expand_vpc_loongson_bcast,
	mips_expand_vector_init): Use TARGET_LOONGSON_MMI instead of
	TARGET_LOONGSON_VECTORS.
	* gcc/config/mips/mips.h (TARGET_LOONGSON_VECTORS): Delete.
	(TARGET_CPU_CPP_BUILTINS): Add __mips_loongson_mmi.
	(MIPS_ASE_DSP_SPEC, MIPS_ASE_LOONGSON_MMI_SPEC): New.
	(BASE_DRIVER_SELF_SPECS): march=loongson2e/2f/3a implies
	-mloongson-mmi.
	(SHIFT_COUNT_TRUNCATED): Use TARGET_LOONGSON_MMI instead of
	TARGET_LOONGSON_VECTORS.
	* gcc/config/mips/mips.md (MOVE64, MOVE128): Use
	TARGET_LOONGSON_MMI instead of TARGET_LOONGSON_VECTORS.
	(Loongson MMI patterns): Include loongson-mmi.md instead of
	loongson.md.
	* gcc/config/mips/mips.opt (-mloongson-mmi): New option.
	* 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,
	check_vect_support_and_set_flags):Use mips_loongson_mmi instead
	of mips_loongson when check et-is-effective-target.
