cpuid.h: New file.

	* gcc/config/i386/cpuid.h: New file.
	* gcc/config/i386/driver-i386.c: Include cpuid.h.
	(describe_cache): Shrink size and line strings to 100 bytes.
	(detect_caches_amd): Return "" for unsupported max_ext_level.
	Use __cpuid function.
	(detect_caches_intel): Return "" for unsupported max_level.
	Use __cpuid function.
	(host_detect_local_cpu): Change feature flag variables to
	unsigned int.  Initialize only extended feature flag variables.
	Use __get_cpuid_max to determine max supported cpuid level.
	Use __cpuid function to determine supported features.  Fix
	calculation of family id.  Remove is_amd and check signature
	directly.  Check for Geode signature.  Handle family 4 id.
	[PROCESSOR_GENERIC32]: New default for unknown family id. Move
	cpu discovery code to other part of the function.

	for sub-architecture.
	[PROCESSOR_PENTIUMPRO]: Simplify cpu discovery code.
	[PROCESSOR_K8]: Add k8-sse3 architecture.
	[PROCESSOR_GENERIC64]: Remove.
	* gcc/config/i386/x-i386 (driver-i386.o): Depend on cpuid.h.
	* gcc/config/i386/crtfastmath.c: Include cpuid.h.  Use __get_cpuid
	to check for SSE and FXSAVE support.
	* gcc/config/i386/t-crtfm (crtfastmath.o): Depend on cpuid.h.
	Add -minline-all-stringops.
	* gcc/config.gcc (i[34567]86-*-*): Add cpuid.h to extra_headers.
	(x86_64-*-*): Ditto.
