[PATCH] D55781: Make CC mangling conditional on the ABI version

[Reid Kleckner via Phabricator via cfe-commits]

rnk added a comment.

@rsmith asked if we should make this mangling conditional on the ABI version. I implemented it here, let me know if you think it's worth the extra code complexity. Our mingw ABI hasn't been particularly stable, but I think going forward we'll want to start mangling new calling convention attributes (regcall, maybe?) this way, and we'll want to make it conditional on the ABI version using something like this code structure.
