82ae0152a7 Allow messaging expression as foreach's collection expression.

1b0ea82459 Substituted all instances of the string "Objc" for "ObjC". This fixes 
some naming inconsistencies in the names of classes pertaining to Objective-C
support in clang.

7b1b947ca1 twiks based on Chris's comment. No need to iterate thru a list of declarations 
in a foreach-statement which is illegal (but not yet caught) .

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.

0ee0b0ab8c Move the null pointer constant check from Sema::CheckSingleInitializer/ActOnCallExpr/CheckMessageArgumentTypes/ActOnReturnStmt to Sema::CheckSingleAssignmentConstraints. This makes sure all null pointer assignments are considered compatible.

9def2b15c1 Phase 2 of making the Decl class more lightweight... 
Move Identifier/Loc instance variables (and associated getters/setters) down from Decl to ScopedDecl/FieldDecl.

Objc AST's can now inherit from Decl without getting instance variables and types that are C specific. For now, I am keeping NextDeclarator, since I believe it may be useful to ObjC. If not, it can be moved later.

to compute its extent.

42a350a18a Finish converting SwitchStmt AST to source ranges. 
Move DumpSourceRange() to DumpStmt().

Now -parse-ast-dump will display source range info for all stmts/exprs.

One day we should implement the source range protocol for Decls.

cac27a5478 Fix a bug/missing-feature Ted noticed: the 'unused' warning should not 
warn about the last stmt in a stmtexpr, f.e. there should be no warning for:

int maxval_stmt_expr(int x, int y) {
  return ({int _a = x, _b = y; _a > _b ? _a : _b; });

cff94fa201 Added extra semantic checking to do basic detection of 
"return of stack addresses."  ParseReturnStmt now calls CheckReturnStackAddr
to determine if the expression in the return statement evaluates to an
address of a stack variable.  If so, we issue a warning.
