DebugInfo: Reorder definitions of MDLocation and MDFile, NFC

Browse Source 
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.)
