[Clang] Be less strict about diagnosing null pointer dereference. (#149648)
In #143667, we made constant evaluation fail on `*null_ptr`, as this is
UB. However, `&(*(foo*)0)` seems to be a common pattern, which made
#143667 too disruptive.
So instead of failing the evaluation, we note the UB, which let clang
recovers when checking for constant initialization.
Fixes #149500
