bf23953 by Guy Harris (guy@xxxxxxxxxxxx):
Only turn -msse4.2 on for ws_mempbrk_sse42.c, and don't always build it.
Move all the SSE 4.2 stuff to wsutil/CMakeLists.txt.
Don't put ws_mempbrk_sse42.c in WSUTIL_FILES by default; add it if we
think the compiler supports compiling for SSE 4.2.
Add -msse4.2 to its COMPILE_FLAGS, but don't add it to any other
compiler flags - we don't want to build anything else with -msse4.2 by
default, as the only code that uses SSE 4.2 instructions but *only* does
so if the processor supports it is our mempbrk implementation. (And
*add* it, don't *replace* the existing flags with -msse4.2; that way,
-Werror is left in there as well.)
