[PATCH] D40181: [libcxx] Allow to set locale on Windows.

[Andrey Khalyavin via Phabricator via cfe-commits]

halyavin created this revision.

Fix the problem PR31516 <https://bugs.llvm.org/show_bug.cgi?id=31516> with setting locale on Windows by wrapping _locale_t with a pointer-like class.

Reduces 74 test failures in std/localization test suite to 47 test failures (on llvm clang, Visual Studio 2015). Number of test failures doesn't depend on the platform (x86 or x64).
