e101f9548e Hack Sema::MergeTypeDefDecl() to silently ignore duplicate typedef's in system headers files. 
A bizarre, non-standard hook that many compilers appear to implement (sigh:-).

1e7873642b Many refinements to Sema::MergeVarDecl(). This routine still needs some re-work to fully handle tentative decls. 
This includes a fix to bz1908.

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().

e6b0ec8b5e Fix Sema::ActOnDeclarator() to call MergeFunctionDecl for function decls that aren't in scope. Since C functions are in a flat namespace, we need to give them special treatment (when compared with variables and typedefs).

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.

1daa3cfbae TargetInfo no longer includes a reference to SourceManager. 
Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:

    FullLoc.getManager().someMethod(FullLoc.getLocation());
    
instead we have:

    FullLoc.someMethod();
    
Modified TextDiagnostics (and related classes) to use this short-hand.

f727faf2ed Explicitly set the string literal type from "char *" to "constant array of char". 
At this point, I am fairly certain the front-end is correct. Unfortunately, the back-end is still unhappy.

That said, I've commented out the two lines in globalinit.c that are causing problems.

Chris, please have a look...thanks!

2c20c38ced Have Sema::CheckConstantInitList skip semantic analysis when the element type is a record (until we implement the FIXME). This removes a bogus error for the following code... 
snarofflocal% cat bug.m

#import <Foundation/NSGeometry.h>

#define NUMHELICOPTERRECTS 5

static NSRect helicopterRects[NUMHELICOPTERRECTS] = {
    {{27, 0}, {18, 11}},	// Bottom
    {{0, 8}, {4, 11}},		// Tail
    {{0, 16}, {50, 1}},
    {{22, 5}, {18, 12}},	// Body
    {{0, 10}, {42, 3}}
