John Baldwin b9dda9d6fe Fix a few nits in the earlier changes to prevent local information leakage
in AMD FPUs:
- Do not clear the affected state in the case that the FPU registers for
  the thread that already owns the FPU are changed via fpu_setregs().  The
  only local information the thread would see is its own state in that
  case.
- Fix a type mismatch for the dummy variable used in a "fld".  It accepts
  a float, not a double.
