MFC 238450,250152-250153,250415:
- Add support for the XSAVEOPT instruction use.
- The check to ensure that xstate_bv always has XFEATURE_ENABLED_X87 and
  XFEATURE_ENABLED_SSE bits set is not needed.  CPU correctly handles
  any bitmask which is subset of the enabled bits in %XCR0.
- Partially saved extended state must be handled always, i.e. for both
  fpu-owned context, and for pcb-saved one.
- Correct the type for the literal used on the left side of the shift up
  to 63 bit positions.

  Do not fill the save area and do not set the saved bit in the xstate
  bit vector for the state which is not marked as enabled in xsave_mask.
