DebugInfo: Reorder definitions of MDLocation and MDFile, NFC
Move definition of `MDLocation` after `MDLocalScope` so that the latter is available for casts in the former. Similarly, move the definition of `MDFile` as early as possible so that other classes can cast to it in their definitions. (Follow-up commits will take advantage of this.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233096 91177308-0d34-0410-b5e6-96231b3b80d8
