[AArch64] ARMv8.2 command line and feature macros support
* config/aarch64/aarch64-arches.def: Add "armv8.2-a".
* config/aarch64/aarch64.h (AARCH64_FL_V8_2): New.
(AARCH64_FL_F16): New.
(AARCH64_FL_FOR_ARCH8_2): New.
(AARCH64_ISA_8_2): New.
(AARCH64_ISA_F16): New.
(TARGET_FP_F16INST): New.
(TARGET_SIMD_F16INST): New.
* config/aarch64/aarch64-option-extensions.def ("fp16"): New entry.
("fp"): Disabling "fp" also disables "fp16".
* config/aarch64/aarch64-c.c (arch64_update_cpp_builtins): Conditionally define
__ARM_FEATURE_FP16_SCALAR_ARITHMETIC and __ARM_FEATURE_FP16_VECTOR_ARITHMETIC.
