.def file for each library. This means that adding a diagnostic
to sema doesn't require all the other libraries to be rebuilt.

causing assertion failures in getSExtValue().
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>)

- 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.

Performance impact for -fsyntax-only on Cocoa.h (with Cocoa.h in the PTH file):
- PTH generation time improves by 5%
- PTH reading improves by 0.3%.

- When it's safe, ActionResult uses the low bit of the pointer for
the "invalid" flag rather than a separate "bool" value. This keeps
GCC from generating some truly awful code, for a > 3x speedup in the
result-passing microbenchmark.
- When DISABLE_SMART_POINTERS is defined, store an ActionResult
within ASTOwningResult rather than an ASTOwningPtr. Brings the
performance benefits of the above to smart pointers with
DISABLE_SMART_POINTERS defined.
Sadly, these micro-benchmark performance improvements don't seem to
make much of a difference on Cocoa.h right now. However, they're
harmless and might help with future optimizations.
