Remove wrappers and other cruft intended to support SVID, mistakes in
...
C90, and other arcana. Most of these features were never fully
supported or enabled by default.

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.

Mark inline stmxcsr instructions as volatile, since this appears to be
...
the only way to convince gcc that they read the MXCSR. The volatile
annotation may be needed elsewhere as well.
