[PATCH 2/5] fix assignment: pointer to __pure/__noreturn function to void *

[Luc Van Oostenryck <luc.vanoostenryck@xxxxxxxxx>]

It's fine for a pointer to a __pure or a __noreturn function
to be assigned to a void pointer (since this pointer can't
be used to make an indirect function call without another cast).

Ensure this by ignoring the corresponding modifiers when checking
such assignments.
