[AArch64] Add basic FP16 support
gcc/:
* config/aarch64/aarch64-builtins.c (aarch64_fp16_type_node): New.
(aarch64_init_builtins): Make aarch64_fp16_type_node, use for __fp16.
* config/aarch64/aarch64-modes.def: Add HFmode.
* config/aarch64/aarch64.h (TARGET_CPU_CPP_BUILTINS): Define
__ARM_FP16_FORMAT_IEEE and __ARM_FP16_ARGS. Set bit 1 of __ARM_FP.
* config/aarch64/aarch64.c (aarch64_init_libfuncs,
aarch64_promoted_type): New.
(aarch64_float_const_representable_p): Disable HFmode.
(aarch64_mangle_type): Mangle half-precision floats to "Dh".
(TARGET_PROMOTED_TYPE): Define to aarch64_promoted_type.
(TARGET_INIT_LIBFUNCS): Define to aarch64_init_libfuncs.
* config/aarch64/aarch64.md (mov<mode>): Include HFmode using GPF_F16.
(movhf_aarch64, extendhfsf2, extendhfdf2, truncsfhf2, truncdfhf2): New.
* config/aarch64/iterators.md (GPF_F16): New.
gcc/testsuite/:
* gcc.target/aarch64/f16_movs_1.c: New test.
