[AArch64] Support the 'crc' extension in -march and -mcpu options.
gcc/
* config/aarch64/aarch64-option-extensions.def: Add
AARCH64_OPT_EXTENSION of 'crc'.
* config/aarch64/aarch64.h (AARCH64_FL_CRC): New define.
(AARCH64_ISA_CRC): Ditto.
* doc/invoke.texi (-march and -mcpu feature modifiers): Add
description of the CRC extension.
