10b01832c3 Replace fegetmask() and fesetmask() with feenableexcept(), 
fedisableexcept(), and fegetexcept().  These two sets of routines
provide the same functionality.  I implemented the former as an
undocumented internal interface to make the regression test easier to
write.  However, fe(enable|disable|get)except() is already part of
glibc, and I would like to avoid gratuitous differences.  The only
major flaw in the glibc API is that there's no good way to report
errors on processors that don't support all the unmasked exceptions.

15d3b4db61 Define FE_TONEAREST, FE_TOWARDZERO, FE_UPWARD, FE_DOWNWARD and _ROUND_MASK to 
unbreak the build for arm.

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.

60b22cf1c2 Only use rfs and wfs if ARM_HARD_FLOAT is defined, and use stubs if it is not, 
in order to unbreak arm make world. The right way to do it with soft floats
will be figured out later.

19220bc13f Add an fenv.h implementation for the arm port. 
It does not appear to be possible to cross-build arm from i386 at the
moment, and I have no ARM hardware anyway.  Thus, I'm sure there are
bugs.  I will gladly fix these when the arm port is more mature.
