operator delete isn't annotated with `captures(none)`

[philnik777]

I'm not 100% certain that it would be correct to annotate operator delete with captures(none), but operator new is already being annotated with noalias, even though that's technically not guaranteed to be correct. Should Clang add captures(none) with -fassume-sane-operator-new?
