8f5b00d375 Move math_check_force_underflow macros to separate math-underflow.h. 
This patch continues cleaning up math_private.h by moving the
math_check_force_underflow set of macros to a separate header
math-underflow.h.

This header is included by the files that need it rather than from
math_private.h.  Moving these macros to a separate file removes the
math_private.h uses of macros from float.h, so the inclusion of
float.h in math_private.h is also removed; files that were depending
on that inclusion are fixed to include float.h directly.  The
inclusion of math-barriers.h from math_private.h will be removed in a
separate patch.

Tested for x86_64 and x86.  Also tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by this patch.

2f49ce7d62 Use libm_alias_float in flt-32. 
This patch makes flt-32 libm functions use libm_alias_float to define
public interfaces (in cases where _Float32 aliases of those interfaces
would be appropriate, so not for finitef / isinff / isnanf).

Tested for x86_64.  Also tested with build-many-glibcs.py that
installed stripped shared libraries are unchanged by the patch.

41a359e22f Add nextup and nextdown math functions 
TS 18661 adds nextup and nextdown functions alongside nextafter to provide
support for float128 equivalent to it.  This patch adds nextupl, nextup,
nextupf, nextdownl, nextdown and nextdownf to libm before float128 support.

The nextup functions return the next representable value in the direction of
positive infinity and the nextdown functions return the next representable
value in the direction of negative infinity.  These are currently enabled
as GNU extensions.
