libstdc++: Adjust friend declarations to work with Clang

Browse Source 
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.
