warn about the last stmt in a stmtexpr, f.e. there should be no warning for:

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

be passed as an (optional) argument to StmtPrinter to customize
printing of AST nodes.

Used new PrinterHelper interface to enhance printing and visualization
of CFGs.  The CFGs now illustrate the semantic connectives between
statements and terminators, wheras in the previous printing certain
expressions would (visible) be printed multiple times to reflect which
expressions used the results of other expressions.

The end result is that the CFG is easier to read for flow of
expression values (following principles similar to the LLVM IR).

Removed Sema::VerifyConstantArrayType(). With the new Array/ConstantArray/VariableArray nodes, this
routine was causing more trouble than it was worth. Anders/Chris noticed that it could return an error code
without emiting a diagnostic (which results in an silent invalid decl, which should *never* happen). In addition,
this routine didn't work well for typedefs and field decls. Lastly, it didn't consider that initializers aren't
in place yet.

Added Type::getAsConstantArrayType(), Type::getAsVariableArrayType(), Type::getAsVariablyModifiedType(),
and Type::isVariablyModifiedType();

Modified Sema::ParseDeclarator() and Sema::ParseField() to use the new predicates. Also added a FIXME for
the initializer omission. Also added a missing test for "static" @ file scope.

all the stuff in macos math.h, and other stuff as it's added to *Builtins.def.

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...

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:-)

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang x.c -pedantic

introduced by moving "CaseStmt" pointers out of the list of statements
and into the explicit "label" associated with a CFGBlock.  --This
line, and those below, will be ignored--

no statements (or just full of ';' statements).

llvm-svn: 41620

blocks involving only ';' statements.  We now correctly handle the following:

void empty_label() { l1: ; }

llvm-svn: 41619

llvm-svn: 41618

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.

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.

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.
