re PR target/37197 (-msse4 ICE on __builtin_parityl)

	PR target/37197
	* config/i386/driver-i386.c (processor_signatures): New enum.
	(SIG_GEODE): Move from vendor_signatures to processor_signatures.
	(host_detect_local_cpu): For SIG_AMD vendor, check for SIG_GEODE
	processor signature to detect geode processor.
