When printing a std::string_view, print the referenced string as the summary. Support string_view, u32string_view, u16string_view and wstring_view, as we do for std::string and friends. This is based on the existing fomratter for std::string, and just extracts the data and length members, pushing them through the existing string formatter. In testing this, a "FIXME" was corrected for printing of non-ASCII empty values. Previously, the "u", 'U" etc. prefixes were not printed for basic_string<> types that were not char. This is trivial to resolve by printing the prefix before the "". Differential revision: https://reviews.llvm.org/D112222
