[PATCH] c-family: Use -Wdiscarded-qualifiers for ignored qualifiers in __atomic_*

[Florian Weimer]

This matches other compiler diagnostics.  No test updates are needed
because c-c++-common/pr95378.c does not match a specific -W option.

Fixes commit d2384b7b24f8557b66f6958a05ea99ff4307e75c ("c-family:
check qualifiers of arguments to __atomic built-ins (PR 95378)").

        * c-common.cc (get_atomic_generic_size): Use
        OPT_Wdiscarded_qualifiers instead of
        OPT_Wincompatible_pointer_types.

Jonathan, I assume this was just an oversight in your patch, and there
is no fundamental reason to use -Wincompatible-pointer-types here?

Thanks,
Florian
