[PATCH] D29912: [MS ABI] Correctly mangling vbase destructors

[David Majnemer via Phabricator via cfe-commits]

majnemer created this revision.

They are a little bit of a special case in the mangling. They are always
mangled without taking into account their virtual-ness of the
destructor. They are also mangled to return void, unlike the actual
destructor.

This fixes PR31931.
