Duncan P. N. Exon Smith 9b4250d309 Verifier: Don't call debug info verifier if the module is broken 
If `Verifier` has already found a failure, don't call
`DebugInfoVerifier`.  The latter sometimes crashes in `DebugInfoFinder`
when the former would give a nice message.  The only two cases I found
it crashing are explicit verifier tests I've added:

  - test/Verifier/llvm.dbg.declare-expression.ll
  - test/Verifier/llvm.dbg.value-expression.ll

However, I assume frontends with bugs will create invalid IR as well.

IMO, the `DebugInfoVerifier` should never crash (instead, it should fail
to verify), but subtleties like that will be easier to work out once
it's enabled again.

This is part of PR22777.
