[PATCH] D45015: [Preprocessor] Allow libc++ to detect when aligned allocation is unavailable.

Another approach is `__has_feature` but I don't think it is applicable in this case.

Is there a way right now to detect that aligned allocation is supported by clang, regardless of link time? Asking to make sure we are consistent.
