configure: rework parsing --cpu arguments to support all features unless blacklisted
Keeping an ever growing list of CPUs just to pass -march to the compiler and
enable fast_cmov is a waste of time. Every CPU we know has limitations is
already handled here, so just fallback to enabling everything when a passed in
argument is not one of those.
This will enable optimizations for CPU architectures released in the past 7 or
so years with supported GCC and clang compilers when used as argument in
configure, instead of silently ignoring them.
