[PATCH, AArch64] Add optimized strrchr.

Subject: [PATCH, AArch64] Add optimized strrchr.
Authentication-results: sourceware.org; auth=none

Completing the basic set of strchr like implementations, this patch adds
an implementation of strrchr.  This implementation avoids the overhead
of repeated calls to strchr in the standard C code which can save
significant amounts of time if there are multiple hits on the target
character.

Committed.
