0fe0f1f86f Create and use libc_feupdateenv_test.
We can reduce the number of STMXCSR, and often we can avoid the
call to __feraiseexcept.

4851a949b4 Make inline __isnan, __isinf_ns, __finite generic.
For code generation to stay identical on x86_64, this requires that
we define the fp word manipulation macros before including the
generic header.
