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.)

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.

Call _M_extract_* functions family through temporary int objects, so
it doesn't convert from lvalue to rvalue through a temporary in AVR
because of the incompatible types used in AVR-Libc.
This fixes compilation errors with AVR-Libc while compiling libstdc++
for AVR target.
