Steve Naroff 43b8f7fa4f Sema::ParseCastExpr() missing call to UsualUnaryConversions().
The following case now works...

void empty(void * a ) {}

void test()
{
    unsigned char A[4]; 
    empty( (void *) A); 
}

Thanks to Patrick Flannery for finding this...

Steve Naroff d57fa94148 Final phase of array cleanup (for now), removing a FIXME from yesterday.
Moved several array constraints checks from Sema::VerifyConstantArrayType() to
Sema::GetTypeForDeclarator(). VerifyConstantArrayType() is now very simple, and
could be removed eventually.

Now, we get the following (correct) messages for BlockVarDecls:-)

Ted Kremenek 55e91e8bdd Fixed a bug in constructing CFG blocks for case statement fall-through
introduced by moving "CaseStmt" pointers out of the list of statements
and into the explicit "label" associated with a CFGBlock.  --This

Ted Kremenek bbad8ce2e7 Fixed bug where the CFG would fail to build when an 'if' statement had
an empty then or else block (or contained only ';' statements).

For example, we now handle the following:

int empty_else() { if (0) { int a; } else ; }
int empty_then() { if (0) ; else { int a; } }

Thanks to Nico Weber for spotting this problem.

Steve Naroff 90dfdd5774 Polish yesterday's Array/ConstantArray/VariableArray rewrite, removing a couple FIXME's.
Refactored Array/VariableArray, moving SizeModifier/IndexTypeQuals back up to Array. These
attributes are not specific to VLA's. Most of them are specific to array parameter types.

Ted Kremenek 14f0d1a85a Fixed bug for CaseStmt where the child_begin/child_end methods were not
including the expressions in the case statement itself (not the body of
the case).

This required moving SubStmt out of SwitchCase into CaseStmt and DefaultStmt
respectively.  getSubStmt() now is a virtual call for SwitchCase, but is
a direct (static) call for CaseStmt and DefaultStmt.

Chris Lattner 11e30d355e Teach the stmtdumper to dump location/range info when a SourceMgr is available.
For example, -parse-ast-dump now prints:

static inline int __inline_isinff(float __x)
(CompoundStmt 0x2409a20
  (ReturnStmt 0x2409a10
    (BinaryOperator 0x24099f0 'int' <///usr/include/architecture/i386/math.h:183:63, col:102> '=='
      (CallExpr 0x24098f0 'float' <col:63, col:82>
        (ImplicitCastExpr 0x24098e0 'float (*)(float)' <col:63>
          (DeclRefExpr 0x2409880 'float (float)' <col:63> Decl='__builtin_fabsf' 0x2409840))
        (DeclRefExpr 0x24098a0 'float' <col:79> Decl='__x' 0x2409810))
      (CallExpr 0x24099c0 'float' <col:87, col:102>
        (ImplicitCastExpr 0x2409870 'float (*)(void)' <col:87>
          (DeclRefExpr 0x2409980 'float (void)' <col:87> Decl='__builtin_inff' 0x2409940))))))

where it only prints filename/line# if it changes from the previous value.  We 
really need loc info on stmts though, like we have on exprs.

Steve Naroff 5c13180a27 Fix the following redefinition errors submitted by Keith Bauer...
[dylan:~/llvm/tools/clang] admin% cat tentative_decls.c 
// incorrectly generates redefinition error
extern int array[3];
int array[3];

// incorrectly generates a redefinition error
extern void nup(int a[3]);
void nup(int a[3]) {}

It turns out that this exposed a fairly major flaw in the type system,
array types were never getting uniqued! This is because all array types
contained an expression, which aren't unique.

To solve this, we now have 2 array types, ConstantArrayType and
VariableArrayType. ConstantArrayType's are unique, VAT's aren't.

This is a fairly extensive set of fundamental changes. Fortunately,
all the tests pass. Nevertheless, there may be some collateral damage:-)
If so, let me know!

Chris Lattner 84ca3762ae Previous commit should have been:
Use Ted's child walking interface to allow the dumper to walk the tree 
  in one place and only have node-specific callbacks worry about 
  formatting the nodes (instead of formatting the nodes plus walking the
  tree).

This commit eliminates now default cases by letting them fall through with
the normal visitor stuff.

Ted Kremenek 71eca01291 Added an (optional) explicit "Label" statement to CFGBlock. If a
block begins with a label or case statement, CFGBlock::getLabel() will
return the corresponding LabelStmt/CaseStmt/DefaultStmt.

LabelStmts and SwitchCases no longer appear within the "executable"
statements of a CFGBlock.

More cleanups on visualization/pretty-printing of CFGs (less verbose).
