Migrate most of the location setting within the larger API in CGDebugInfo and
update a lot of callers.
Remove the existing file/scope change machinery in UpdateLineDirectiveRegion
and replace it with DILexicalBlockFile usage.

 - This disables the system include directories, but not the compiler builtin
   directories. Useful for projects that want to use things like the intrinsic
   headers, but are otherwise freestanding.

 - I'm willing to reconsider the option naming, I also considered providing an
   explicit -builtinc (which would match -nobuiltininc), but this is more
   consistent with existing options.

The main motivation was to do typo correction in C++ "new" statements,
though picking it up in other places where type names are expected was
pretty much a freebie.

Rework construction of CXXForRangeStmt not to recycle the same DeclRefExpr in multiple subexpressions.  This breaks the tree structure
