Rewrite a complex expression in wxClassInfo::IsKindOf() as several statements to avoid what looks like a gcc optimizer bug as it was dereferencing m_baseInfo1 pointer even when it was null. The new version is not completely equivalent to the old one as it doesn't check for info == NULL which is not really necessary, but this is just a side effect and doesn't affect anything, the important change is avoiding doing everything in a single expression. Closes #17483.
