[Nasm-cvs] Add XSAVE instruction features (CPU feature is bogus, but oh well.)

[H. P. A. <hp...@zy...>]

Date: Thu, 14 Feb 2008 11:25:14 -0800

Add the XSAVE group of instructions: XSAVE, XRSTOR, XGETBV, XSETBV.
The CPU feature information is bogus, but so is our entire handling of
CPU feature sets for anything but the bare necessities (long jump
emulation, etc.)
