Saleem Abdulrasool f1b30c41ad Handle function name conflicts in _LIBCPP_MSVCRT mode
Visual Studio's SAL extension uses a macro named __deallocate. This macro is
used pervasively, and gets included through various different ways. This
conflicts with the similarly named interfaces in libc++. Introduce a undef
header similar to __undef_min_max to handle this. This fixes a number of errors
due to the macro replacing the function name.
