Also changed FunctionTypeProto to be allocated with 8-byte alignment (noticed by Doug). I couldn't think of any reason to allocate on 16-byte boundaries. If anyone remembers why we were doing this, let me know!

Remove many references to ASTContext::getAllocator(), replacing them with calls to the recently added placement new (which uses ASTContext's allocator for memory). Also added ASTContext::Deallocate().

This will simplify runtime replacement of ASTContext's allocator. Keeping the allocator private (and removing getAllocator() entirely) is also goodness.

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

to sema doesn't require all the other libraries to be rebuilt.

Patch by Anders Johnsen!

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.

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?!

 - gcc appears to be classifying <1 x double> as INTEGER which is
   odd. Will investigate later.

- 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>)

PTH: Use Token::setLiteralData() to directly store a pointer to cached spelling data in the PTH file.  This removes a ton of code for looking up spellings using sourcelocations in the PTH file.  This simplifies both PTH-generation and reading.

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.
