I realized looking at the sigalgs parser that I messed up the space-splitting logic slightly. If the CPU features are "foo bar baz", it would not parse "baz". This doesn't particular matter (the last one is "crc32"), but better to parse it correctly. Fix this and add a unit test. While I'm here, may as well add a fuzzer too.
