No functionality change. It should suffice to check the type of a debug info metadata, instead of calling Verify. For cases where we know the type of a DI metadata, use assert. Also update testing cases to make them conform to the format of DI classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185135 91177308-0d34-0410-b5e6-96231b3b80d8
