Detailed Description

Base class for scope-like contexts.

Base class for lexical scopes and types (which are also declaration contexts).

TODO: Separate the concepts of declaration contexts and lexical scopes.

Return the raw underlying file.

A DIFile is a DIScope, but it doesn't point at a separate file (it is the file). If this is an DIFile, we need to return this. Otherwise, return the first operand, which is where all other subclasses store their file pointer.
