[PATCH, AArch64] Add optimized strcpy implementation

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

This patch adds an optimized implementation of strcpy for AArch64.  The
main advantage of this version over the generic C version is that it can
handle strings that are not aligned much more efficiently.  However, for
all but the shortest of strings it is faster even for aligned strings
since it can handle up to 16 bytes per iteration.

Committed to trunk.
