Introduce a new PresumedLoc class to represent the concept of a location
...
as reported to the user and as manipulated by #line. This is what __FILE__,
__INCLUDE_LEVEL__, diagnostics and other things should follow (but not
dependency generation!).
This patch also includes several cleanups along the way:
- SourceLocation now has a dump method, and several other places
that did similar things now use it.
- I cleaned up some code in AnalysisConsumer, but it should probably be
simplified further now that NamedDecl is better.
- TextDiagnosticPrinter is now simplified and cleaned up a bit.
This patch is a prerequisite for #line, but does not actually provide
any #line functionality.
