Submit #3264: [PATCH] Clarify XSAVE features, and always use XSAVE

* Target version: master
----------------------------------------
1) Introduce npx_xcr0_mask, to keep track of which XCR0 features are enabled
   system-wide.

2) Always use XSAVE regardless of whether AVX is supported or not. XSAVE may be
   supported without AVX, on certain CPUs and also under hypervisors that expose
   XSAVEOPT without AVX.
