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.
