testing compatibility.  This is necessary for some constructs, like merging
redeclarations.

Also, there are some ObjC changes to make sure that 
typesAreCompatible(a,b) == typesAreCompatible(b,a).  I don't have any 
ObjC code beyond the testsuite, so please tell me if there are any cases 
where this doesn't behave as expected.

Fix ASTContext::getObjCEncodingForType() to limit the type info for structure bodies (mimics gcc's adhoc rules).
This fixes <rdar://problem/6140902> clang ObjC rewriter: If a class contains a struct ivar with a lot of members, ...

 - Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

   SourceLocation.h)
 - Move ASTContext constructor into implementation

Finally fix PR2189.  This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

First, fix canonical type handling of these, since protocol qualified id's are always
canonical.  Next, enhance SemaType to actually make these when used (instead of int)
allowing them to actually be used when appropriate.  Finally remove a bunch of logic
relating to the mishandling of canonical types with protocol-qual id's.  This fixes

1) add a new ASTContext::getFloatTypeSemantics method.
2) Use it from SemaExpr.cpp, CodeGenTypes.cpp and other places.
3) Change the TargetInfo.h get*Format methods to return their 
   fltSemantics byref instead of by pointer.
4) Change CodeGenFunction::EmitBuiltinExpr to allow builtins which
   sometimes expand specially and othertimes fall back to libm.
5) Add support for __builtin_nan("") to codegen, cases that don't pass
   in an empty string are currently lowered to libm calls.
6) Fix codegen of __builtin_infl.

integers which have the same width and different signedness work 
correctly. (The testcase in PR2501 uses a comparison between long and 
unsigned int).

  Added TagKind enum.
  Added getTagKind() method.
  Added convenience methods: isEnum(), isStruct(), isUnion(), isClass().
-RecordDecl/CXXRecordDecl::Create() accept a TagKind enum instead of a DeclKind one.

I'm reasonably confident this is accurate, at least for X86.  I'll
