A WIP patch makes `DIDescriptor` accessors more strict, which in turn causes the `DebugInfoFinder` to crash on wrongly typed `!dbg` attachments. Catch that error up front in `Verifier::visitInstruction()`. Also remove a test that we "handle" invalid `!dbg` attachments, added back in r99938. We don't want to handle those anymore. Note: I'm *not* recursing and verifying the debug info graph reachable from this node; that work is already done by `verifyDebugInfo()`. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232834 91177308-0d34-0410-b5e6-96231b3b80d8
