b51483f48f Finish implementing P0426R1 "Constexpr for std::char_traits" for C++17 
As discussed in PR c++/80265 ("__builtin_{memcmp,memchr,strlen} are
not usable in constexpr functions"), use __builtin_constant_p to tell
whether we can defer to a constexpr algorithm.

I used __always_inline__ just to be thorough.  It isn't really really
necessary as far as I could determine.

Changes like these:

	 if (__n == 0)
	   return 0;
 -	return wmemcmp(__s1, __s2, __n);
 +	else
 +	  return wmemcmp(__s1, __s2, __n);

are necessary otherwise G++ complains that we're calling a
non-constexpr function, which looks like a a manifestation of PR67026
to me.

74106ead26 [libstdc++-v3] Fix detection of obsolete isnan 
libstdc++-v3 configure checks whether old glibc inline definitions
of isnan would conflict with the libstdc++-v3 definitions and
works around them if so.  But if g++ 6.x build A is used to build
another g++ 6.x B, the configure step for B will pick up the math.h
installed alongside A instead of the glibc version.  configure will
then assume that the workaround isn't necessary, leaving B with a
broken cmath.

isinf already worked around this.  This patch extends the same fix
to isnan.  (Thanks to George for the fix.)

b333e8ebb0 PR libstdc++/60936 reduce coupling between objects in libstdc++.a 
Move explicit instantiation definitions for string I/O functions into
their own files so that iostream and locale definitions are not needed
for uses of strings without I/O. Move functions for throwing C++11
exceptions into the individual files defining the exception types, so
that using any of the functions from functexcept.cc doesn't pull in
large pieces of the C++11 library. Finally, avoid using __int_to_char in
snprintf_lite.cc to avoid pulling in locale-inst.cc for one function.
