This PR adds runtime SIMD instruction set detection. It does so by using
__builtin_cpu_supportsif it's available on x86-64.Note: I'm not sure if this will work on Windows if the compiler isn't
gccorclang. In that case it would fall back to the scalar string scan code.I believe this will resolve #989.
