This reverts commit 5e5e2019ee.
This change was proposed in https://cmake.org/Bug/view.php?id=13194 to
catch some Clang warnings concerning invalid -m flags, but it is causing
legitimate breakage when setting CMAKE_C_FLAGS=-gsplit-dwarf.
CMakeFiles/CMakeError.log shows:
/usr/bin/clang -gsplit-dwarf -DC__W_VALID CMakeFiles/cmTC_04cc8.dir/src.c.o -o cmTC_04cc8 -rdynamic
clang-3.7: warning: argument unused during compilation: '-gsplit-dwarf'
With the additional regex, basic checks (like -Wall but also -fPIE) are
incorrectly reported as unsupported. Follow upstreams action here and
remove it, it is still not present as of CMake 3.3.2.

Correctly detect that XCode7Beta1 does not support -fno-delete-null-pointer-checks
by adding a new regex.

For -f and -m flags that don't apply to the target architecture(?),
Clang doesn't fail but does print a warning "argument unused during
compilation: '-{flag}'". Catch that and treat it as a failure
indication, so we don't use that flag.
