This patch does not touch any existing code and is only meant to be a tool for future patches so that simple source files can more easily be maintained to target multiple VEC classes. There is no difference in the objdump of libc.so before and after this patch. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
