This patch enable guest to use XSAVE/XRSTORE instructions.
We assume that host_xcr0 would use all possible bits that OS supported.
And we loaded xcr0 in the same way we handled fpu - do it as late as we can.

Hi Marcelo & Avi
How about patch 1 and 2 in this series? They are used to enable XSAVE cpuid.

Notice the first three patches applied to uq/master branch of qemu-kvm, the
last one
applied to qemu-kvm master branch. And the last one would only apply after the
first three merged in master branch.
Based on upstream xsave related fields.

Would send out XSAVE patch after the upstream ones have been merged, since the
patch would be affected by the merge.

Enable XSAVE/XRSTORE for guest.
Change from V1:
1. Use FPU API.
2. Fix CPUID issue.
3. Save/restore all possible guest xstate fields when switching. Because we
don't know which fields guest has already touched.
