aarch64-arches.def: Add "armv8.1-a".
2015-06-16 Matthew Wahab <matthew.wahab@arm.com>
* config/aarch64/aarch64-arches.def: Add "armv8.1-a".
* config/aarch64/aarch64-options-extensions.def: Update "fP",
"simd" and "crypto". Add "lse", "pan", "lor" and "rdma".
* gcc/config/aarch64/aarch64.h (AARCH64_FL_LSE): New.
(AARCH64_FL_PAN): New.
(AARCH64_FL_LOR): New.
(AARCH64_FL_RDMA): New.
(AARCH64_FL_FOR_ARCH8_1): New.
* doc/invoke.texi (AArch64 Options): Add "armv8.1-a" to
