* config/aarch64/aarch64.h (AARCH64_FL_RDMA): New.
(AARCH64_FL_V8_1): Renumber.
(AARCH64_FL_FOR_ARCH8_1): Add AARCH64_FL_RDMA.
(AARCH64_ISA_RDMA): Use AARCH64_FL_RDMA.
* config/aarch64/arm_neon.h: Use +rdma instead of arch=armv8.1-a.
* doc/invoke.texi (AArch64 Options): Mention +rmda in -march docs. Add
rdma to feature modifiers list.
gcc/testsuite/
