    x86: fix XCR0 handling
    
    - both VMX and SVM ignored the ECX input to XSETBV
    - both SVM and VMX used the full 64-bit RAX when calculating the input
      mask to XSETBV
    - faults on XSETBV did not get recovered from
    
    Also consolidate the handling for PV and HVM into a single function,
    and make the per-CPU variable "xcr0" static to xstate.c.

commit 10f969150025498fe27d985f9021a68f8c7acc31
Author: Jan Beulich <jbeulich@xxxxxxxx>

    x86: preserve FPU selectors for 32-bit guest code
    
    Doing {,F}X{SAVE,RSTOR} unconditionally with 64-bit operand size leads
    to the selector values associated with the last instruction/data
    pointers getting lost. This, besides being inconsistent and not
    compatible with native hardware behavior especially for 32-bit guests,
    leads to bug checks in 32-bit Windows when running with "Driver
    verifier" (see e.g. http://support.microsoft.com/kb/244617).
    
    In a first try I made the code figure out the current guest mode, but
    that has the disadvantage of only taking care of the issue when the
    guest executes in the mode for which the state currently is (i.e.
    namely not in the case of a 64-bit guest running a 32-bit application,
    but being in kernle [64-bit] mode).
    
    The solution presented here is to conditionally execute an auxiliary
    FNSTENV and use the selectors from there.
    
    In either case the determined word size gets stored in the last byte
    of the FPU/SSE save area, which is available for software use (and I
    verified is being cleared to zero by all versions of Xen, i.e. will not
    present a problem when migrating guests from older to newer hosts), and
    evaluated for determining the operand size {,F}XRSTOR is to be issued
    with.
    
    Note that I did check whether using a second FXSAVE or a partial second
    XSAVE would be faster than FNSTENV - neither on my Westmere (FXSAVE)
    nor on my Romley (XSAVE) they are.
    
    I was really tempted to use branches into the middle of instructions
    (i.e. past the REX64 prefixes) here, as that would have allowed to
    collapse the otherwise identical fault recovery blocks. I stayed away
    from doing so just because I expect others to dislike such slightly
    subtle/tricky code.
