 - Avoid std::string concatenation
 - Use getNameStr().str() when an std::string is really needed.

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.

Token now has a class of kinds for "literals", which include 
numeric constants, strings, etc.  These tokens can optionally have
a pointer to the start of the token in the lexer buffer.  This 
makes it faster to get spelling and do other gymnastics, because we
don't have to go through source locations.

This change is performance neutral, but will make other changes
more feasible down the road.

This is more concrete and useful, tokens aren't really physical objects!

 - gcc is not happy if we start a preprocessed file with
#line 1 "XXX" 1
 - Workaround by making sure file starts with a simple #line change.

Also, factored WriteLineInfo out.

Also, fixed bug where FileType was not being correctly updated.
