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.
