libstdc++: Constrain std::basic_string default constructor [PR113841]
This is needed to avoid errors outside the immediate context when
evaluating is_default_constructible_v<basic_string<C, T, A>> when A is
not default constructible.
This change is not sufficient to solve the problem because there are a
large number of member functions which have a default argument that
constructs an allocator.
libstdc++-v3/ChangeLog:
PR libstdc++/113841
* include/bits/basic_string.h (basic_string::basic_string()):
Constrain so that it's only present if the allocator is default
constructible.
* include/bits/cow_string.h (basic_string::basic_string()):
Likewise.
* testsuite/21_strings/basic_string/cons/113841.cc: New test.
