Implementation Feature Test Macros for P0722R3
Summary:
P1353R0, adopted in San Diego, specified an implementation feature test macro for destroying delete (P0722R3).
The implementation of the feature (https://reviews.llvm.org/rL315662) is not guarded behind a flag, so the macro is not conditional on language version.
