Summary

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 macosx 10.13 or newer"

This is a follow-up to r306722.

Redundant static?

You can drop the last 0 here and two last zeros down below. This will also make the diagnostics less verbose, i.e. instead of iOS 11.0.0 we will show iOS 11.

NIT: Missing // LLVM_CLANG_BASIC_ALIGNED_ALLOCATION_H comment

Can you use AvailabilityAttr::getPlatformNameSourceSpelling instead to be consisted with our unguarded availability warnings?
e.g.:

AvailabilityAttr::getPlatformNameSourceSpelling(S.getASTContext().getTargetInfo().getPlatformName())

This will ensure that the diagnostics will use names like 'macOS' instead of 'macosx'.
