Move debug-info-centred `Metadata` subclasses into their own header/source file. A couple of private template functions are needed from both `Metadata.cpp` and `DebugInfoMetadata.cpp`, so I've moved them to `lib/IR/MetadataImpl.h`. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227835 91177308-0d34-0410-b5e6-96231b3b80d8
