x86: unify CPU feature string names
Move the CPU feature string names to a separate file (common to 32 and 64 bits); additionally, make <asm/cpufeature.h> includable by host code in preparation for including the CPU feature strings in the boot code. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
