445fcabff7 Alternate address spaces work: 
rename QualType::getQualifiers to getCVRQualifiers.
Add some fixme's and clean up some code relevant to qualifiers.
Change ASQualType to contain a Type* instead of a QualType.  
Any CVR qualifiers should be on the outer qual type.

b080ed504e Fix PR2042. One remaining issue: we don't currently diagnose 
int foobar(int);
 int foobar() {}

which requires ifdef'ing out a testcase in predefined-function.c.

bd258284e0 Split out incomplete arrays from VariableArrayType into 
IncompleteArrayType.  This should make code dealing with both incomplete 
and variable length arrays much more readable, plus it allows properly 
making the distinction between isVariableArrayType() and 
isVariablyModifiedType().  The patch is a little big, but it's 
strightforward. so I don't think there should be any issues.

b5fc2551e4 After yesterday's discussion (http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-February/001044.html), decided not to change the semantics of Type::isIncompleteType(). 
This commit simply changes a couple comments to reflect this decision.

78c6cdf95e Replace Sema::CheckVariableInitList, CheckConstantInitList, and CheckForCharArrayInitializer with CheckInitializerListTypes. The new routine now supports struct/union initializers. 
This is a modified version of a patch by Eli Friedman. This version passes all of the clang tests and supports vectors:-)

Note that Eli and I are still unsatisfied the implementation of CheckInitializerListTypes(). We'd like to find a more elegant implementation. Nevertheless, this is a complex part of the standard (and may be hard to simplify). Since the complexity is localized to this routine, we can iterate without too much disruption:-)

98f7203680 - Teach Expr::isConstantExpr() about InitListExpr's (and offsetof, since I noticed it was missing). 
- Rename CheckInitializer() to CheckInitializerTypes().
- Removed the isStatic argument to CheckInitializerTypes() and all of it's subroutines. Checking for constant expressions is now done separately.
- Added CheckForConstantInitializer().

9bad62c72a Merge all the 'assignment' diagnostic code into one routine, decloning 
it from several places.  This merges the diagnostics, making them more
uniform and fewer in number. This also simplifies and cleans up the code.

Some highlights:
1. This removes a bunch of very-similar diagnostics.
2. This renames AssignmentCheckResult -> AssignConvertType
3. This merges PointerFromInt + IntFromPointer which were always treated the same.
4. This updates a bunch of test cases that have minor changes to the produced diagnostics.
