Tested x86_64-linux. Pushed to trunk.

We support <charconv> in C++14 as an extension, but that means that
constexpr static data members are not implicitly inline. Add an
out-of-class definition for C++14 mode.
This fixes a FAIL when -std=gnu++14 is used:
FAIL: 20_util/from_chars/1.cc (test for excess errors)
libstdc++-v3/ChangeLog:
* include/std/charconv (__from_chars_alnum_to_val_table::value):
[!__cpp_inline_variables]: Add non-inline definition.
