[PATCH] D29863: [libc++] Fix PR 31938 - std::basic_string constructors use non-deductible parameter types.

[Eric Fiselier via Phabricator via cfe-commits]

EricWF updated this revision to Diff 88088.
EricWF added a comment.

- Fix the initializer list constructors.
- Add tests for almost every constructor.

The following two examples still do not work:

  std::basic_string s1("hello world", 2); // deduces Allocator = int
  std::basic_string s2("hello world", 0, 2); // deduces Allocator = int

This is because the `Allocator` argument is not normally deduced, and
therefore would not normally accept an integer argument.
