52c326ec78 Prevent nullptr_t-typed exprs from being replaced 
The Use-Nullptr transform was replacing nullptr_t-typed expressions because in
the AST such expressions have an implicit NullToPointer cast around them. Now
the transform ignores these expressions.

Fixes PR15414.

49fe6388b6 Test case for PR-15414 - nullptr_t functions 
The use-null-ptr transform will transform calls to functions that return a
nullptr_t. Even if the function were to only return a null pointer and do
nothing else, this replacement would still be undesired as the behavior and
signature of the function could change in the future.

This adds an XFAILed test case to demonstrate the issue.
