aarch64: Add support for mfloat8x{8|16}_t types

gcc/ChangeLog:

	* config/aarch64/aarch64-builtins.cc
	(aarch64_init_simd_builtin_types): Initialise FP8 simd types.
	* config/aarch64/aarch64-builtins.h
	(enum aarch64_type_qualifiers): Add qualifier_modal_float bit.
	* config/aarch64/aarch64-simd-builtin-types.def:
	Add Mfloat8x{8|16}_t types.
	* config/aarch64/arm_neon.h: Add mfloat8x{8|16}_t typedefs.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/movv16qi_2.c: Test mfloat as well.
	* gcc.target/aarch64/movv16qi_3.c: Ditto.
	* gcc.target/aarch64/movv2x16qi_1.c: Ditto.
	* gcc.target/aarch64/movv3x16qi_1.c: Ditto.
	* gcc.target/aarch64/movv4x16qi_1.c: Ditto.
	* gcc.target/aarch64/movv8qi_2.c: Ditto.
	* gcc.target/aarch64/movv8qi_3.c: Ditto.
	* gcc.target/aarch64/mfloat-init-1.c: New test.
