[aarch64] PR target/94591: Don't generate invalid REV64 insns
This fixes PR94591. The problem was the function aarch64_evpc_rev_local()
matching vector permutations that were not reversals. In particular, prior
to
this patch, this function matched the identity permutation which led to
generating bogus REV64 insns which were rejected by the assembler.
