OK - I was/am trying to clarify you have a particular user/need for this, since no one's had one for many years, so I'm just slightly surprised.

@aprantl - you folks might want to check what the growth of this is like since apple platforms defaults to standalone-debug.
@Jac1494 - have you made any measurements of the size increase of this change? Perhaps a self-host build of clang?
