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.

of this logic was handled by the class RValue, but in reality different
analyses will want more flexibility on how they evaluate different values.

Remove DeclSpec::Invalid, a recently added bool that allowed the parser to detect if the decl spec was invalid.

For now, we will stick with the original strategy - clients of Parse::ParseDeclarationSpecifiers() should never have to know this.

branch ALWAYS be the last successor for a switch-terminated block. This allows
clients to distinguish cases like the following:

switch(...)
  case XXX:
    switch(...) {
      case YYY: ...
    }
    
  case ZZZ: ..
}

In this case, the block with "case ZZZ:" is the default block for the inner
switch statement, but that case is associated with the outer switch statement,
and not the inner one. Clients can test for this behavior by checking if a
successor block is the last one (and thus just assume that this is the "default"
case).

"default" case. In such cases, we now correctly add the CFGBlock representing
the code after the switch statement as a successor to the block terminated by
the switch statement.
