f365db00e5 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.

16919a6cf7 Shift the FPSR contents by the correct amount so feupdateenv() raises 
the correct exceptions from the old environment.
