Verify that debug info intrinsic arguments are valid. (These checks will not recurse through the full debug info graph, so they don't need to be cordoned of in `DebugInfoVerifier`.) With those checks in place, changing the `DbgIntrinsicInst` accessors to downcast to `MDLocalVariable` and `MDExpression` is natural (added isa specializations in `Metadata.h` to support this). Added tests to `test/Verifier` for the new -verify checks, and fixed the debug info in all the in-tree tests. If you have out-of-tree testcases that have started to fail to -verify, hopefully the verify checks are helpful. The most likely problem is that the expression argument is `!{}` (instead of `!MDExpression()`). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232296 91177308-0d34-0410-b5e6-96231b3b80d8
