allocation functions.
This changes the error message Sema prints when an unavailable C++17
aligned allocation function is selected.
Original message: "... possibly unavailable on x86_64-apple-macos10.12"
New message: "... only available on macOS 10.13 or newer"
This is a follow-up to r306722.

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.
