Before we start to rely on valid `!dbg` attachments, add a check to the verifier that `@llvm.dbg.*` intrinsics always have one. Also check that the `scope:` fields point at the same `MDSubprogram`. This is in the context of PR22778. The check that the `inlinedAt:` fields agree has baked for a while (since r234021), so I'll kill [1] the `MDLocalVariable::getInlinedAt()` field soon. [1]: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20150330/269387.html Unfortunately, that means it's impossible to keep the current `Verifier` checks, which rely on comparing `inlinedAt:` fields. We'll be able to keep the checks I'm adding here. If this breaks your out-of-tree testcases, the upgrade script (add-dbg-to-intrinsics.sh) attached to PR22778 that I used for r235040 might fix them for you. llvm-svn: 235048
