libstdc++: Adjust friend declarations to work with Clang
I think this code is valid but it fails with Clang, possibly due to
https://llvm.org/PR38882
Qualifying the names makes it work for all compilers.
libstdc++-v3/ChangeLog:
* include/bits/regex.h (basic_regex, match_results): Qualify
name in friend declaration, to work around Clang bug.
