[Sema] Issue diagnostics if a new/delete expression generates a call to a c++17 aligned allocation/deallocation function that is unavailable in the standard library on Apple platforms. The aligned functions are implemented only in the following versions or later versions of the OSes, so clang issues diagnostics if the deployment target being targeted is older than these: macosx: 10.13 ios: 11.0 tvos: 11.0 watchos: 4.0 The diagnostics are issued whenever the aligned functions are selected except when the selected function has a definition in the same file. If there is a user-defined function available somewhere else, option -Wno-aligned-allocation-unavailable can be used to silence the diagnostics. rdar://problem/32664169 Differential Revision: https://reviews.llvm.org/D34574 llvm-svn: 306722
