  Handle invalid types in the nullPointerConstant AST matcher

Currently, using the nullPointerConstant AST matcher can lead to
assertions in situations where a node to be matched does not have a
valid type associated with it, such as a ParenListExpr. This patch
addresses that by saying such nodes cannot be a null pointer constant.
This addresses PR46353.
