[PATCH] D55791: [libcxx] Simplify conditional definition of _LIBCPP_HAS_NO_ALIGNED_ALLOCATION

[Marshall Clow via Phabricator]

mclow.lists added a comment.

In general, we *do* protect against user-defined defines.  
This, and defining stuff as negative (`_LIBCPP_HAS_NO_XXX`) lets users disable parts of the libc++ functionality by defining the macros.

So I think we should leave this "as is"
