Check accessors of `MDLocation`, and change them to `cast<>` down to the right types. Also add type-safe factory functions. All the callers that handle broken code need to use the new versions of the accessors (`getRawScope()` instead of `getScope()`) that still return `Metadata*`. This is also necessary for things like `MDNodeKeyImpl<MDLocation>` (in LLVMContextImpl.h) that need to unique the nodes when their operands might still be forward references of the wrong type. In the `Value` hierarchy, consumers that handle broken code use `getOperand()` directly. However, debug info nodes have a ton of operands, and their order (even their existence) isn't stable yet. It's safer and more maintainable to add an explicit "raw" accessor on the class itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233322 91177308-0d34-0410-b5e6-96231b3b80d8
