Eric Fiselier 42f9868cd8 Distinguish between library and language support for aligned allocation. ... There are two cases: 1. The library has all it needs to provide align_val_t and the new/delete overloads needed to support aligned allocation. 2. The compiler has actually turned the language feature on. There are times where libc++ needs to distinguish between the two. This patch adds the additional macro _LIBCPP_HAS_NO_LIBRARY_ALIGNED_ALLOCATION which denotes when case (1) does not hold. _LIBCPP_HAS_NO_ALIGNED_ALLOCATION is defined whenever _LIBCPP_HAS_NO_LIBRARY_ALIGNED_ALLOCATION is defined, or when the compiler has not enabled the language feature. Additionally this patch cleans up a number of other macros related to detection of aligned allocation machinery. llvm-svn: 344207		2018-10-11 00:17:24 +00:00
