libstdc++: Use fast_float for long double if it uses binary64 format
We can use the new from_chars implementation when long double and double
have the same representation.
libstdc++-v3/ChangeLog:
* src/c++17/floating_from_chars.cc (USE_STRTOD_FOR_FROM_CHARS):
Define macro for case where std::from_chars is implemented in
terms of strtod, strtof or strtold.
(buffer_resource, valid_fmt, find_end_of_float, pattern)
(from_chars_impl, make_result, reserve_string): Do not define
unless USE_STRTOD_FOR_FROM_CHARS is defined.
(from_chars): Define when at least one of USE_LIB_FAST_FLOAT and
USE_STRTOD_FOR_FROM_CHARS is defined, instead of
_GLIBCXX_HAVE_USELOCALE. Use fast_float for long double when it
is binary64.
