[PATCH] D25451: [libcxx] [test] limited_allocator should be limited_allocator's best friend forever

[Stephan T. Lavavej via cfe-commits]

limited_allocator must grant friendship in order to be rebindable. Found by MSVC, which rebinds allocators in more situations than libc++ does.

This raises an interesting question as to whether libc++ should be validating user-defined allocators more aggressively.
