[PATCH] D12547: Add support for function attribute "disable_tail_calls"

[Akira Hatanaka via cfe-commits]

Marking virtual functions as disable_tail_calls is fine since disable_tail_calls affects the call sites inside the body of the marked function. In your example, it prevents tail call optimization on call sites inside B::g, but doesn't affect call sites in D::g.
