Fix #11401 nullpointer dereference with alignof (#4601)
* checknullpointer: Don't report dereference with alignof

* Refactor unevaluating operator check in checknullpointer

Unifying these ensures the different checks treat the operators the
same.

* Fix FP with _Alignof and null pointer

Just like alignof, _Alignof does not evaluate its operand.

* CheckNullPointer: Also support compiler specific alignof

This fixes #11401 which is about __alignof__. For good measure, also add
the microsoft extensions __alignof and _alignof.
