a uint64_t to verify that the value is in range for the given type,
to help catch accidental overflow. Fix a few places that relied on
getConstant implicitly truncating the value.

If an input constraint refers to an output constraint, it should have the same constraint info as the output constraint. Fixes PR3417

Fix bug in BasicStore::getLValueElement where if the base of an array subscript expression was an ElementRegion we stacked another ElementRegion on top of that.

This fixes PR 3422.

sufficient for now and allows clients to be built on it.

Fix it by making highWordBits actually contain what its name says,
and add some more unit-tests for APInt.
This fixes PR3419.

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.

address space we used up.  Some interesting data:

For c99-intconst-1.c:
6912762 SLocEntry's allocated, 25592386B of Sloc address space used.

For cocoa.h:
26469 SLocEntry's allocated, 10278752B of Sloc address space used.

For carbon.h:
27364 SLocEntry's allocated, 12398141B of Sloc address space used.

Clearly 2G of sloc address space should be enough for anyone?!

- Add the distinction between the 'bug type' and the 'bug description'

HTMLDiagnostics:
- Output the bug type field as HTML comments

scan-build:
- Use the bug type field instead of the bug description for the HTML table.
- Radar filing now automatically picks up the bug description in the title (addresses <rdar://problem/6265970>)

Assorted debug info fixes.
- DW_AT_bit_size is only suitable for bitfields.
- Encode source location info for derived types.
- Source location and type size info is not useful for subroutine_type (info is included in respective DISubprogram) and array_type.

Don't use the Red Zone when dynamic stack realignment is needed.
This could be implemented, but most x86-64 ABIs don't require
dynamic stack realignment so it isn't urgent.
