Move fenv.h soft-float inlines from fenv_private.h to include/fenv.h.
<fenv_private.h> has inline versions of various <fenv.h> functions,
and their __fe* variants, for systems (generally soft-float) without
support for floating-point exceptions, rounding modes or both.
Having these inlines in a separate header introduces a risk of a
source file including <fenv.h> and compiling OK on x86_64, but failing
to compile (because the feraiseexcept inline is actually a macro that
discards its argument, to avoid the need for #ifdef FE_INVALID
conditionals), or not being properly optimized, on systems without the
exceptions and rounding modes support (when these inlines were in
math_private.h, we had a few cases where this broke the build because
there was no obvious reason for a file to need math_private.h and it
didn't need that header on x86_64). By moving those inlines to
include/fenv.h, this risk can be avoided, and fenv_private.h becomes
more clearly defined as specifically the header for the internal
libc_fe* and SET_RESTORE_ROUND* interfaces.
This patch makes that move, removing fenv_private.h includes that are
no longer needed (or replacing them by fenv.h includes in a few cases
that didn't already have such an include).
Tested for x86_64 and x86, and tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by the patch.
