libstdc++: Do not assume existence of char8_t codecvt facet
It is not required that codecvt<char8_t, char, mbstate_t> facet be
supported by the locale, nor is it added as part of the default locale.
This can lead to dangerous behaviour when static_cast.
libstdc++-v3/ChangeLog:
* include/bits/locale_classes.tcc: Remove check for
codecvt<char8_t, char, mbstate_t> facet.
