7a605ba8f7 lib/libc/amd64/string/strcat.S: enable use of SIMD
strcat has a bespoke scalar assembly implementation we
inherited from NetBSD.  While it performs well, it is
better to call into our SIMD implementations if any SIMD
features are available at all.  So do that and implement
strcat() by calling into strlen() and strcpy() if these
are available.

5d053f461c We've been lax about matching END() macros in asm code for some time. This
is used to set the ELF size attribute for functions.  It isn't normally
critical but some things can make use of it (gdb for stack traces).
Valgrind needs it so I'm adding it in.  The problem is present on all
branches and on both i386 and amd64.
