  Log:
  Mark all inline asms that read the floating-point control or status
  registers as volatile.  Instructions that *wrote* to FP state were
  already marked volatile, but apparently gcc has license to move
  non-volatile asms past volatile asms.  This broke amd64's feupdateenv
  at -O2 due to a WAR conflict between fnstsw and fldenv there.
