Avoid using memset on a not-trivial type like nsTabSizes
nsTabSizes is non-trivial only because of the user-defined constructor. The idea desired here is certainly to zero all the members without listing them -- but the very act of doing so with a user-defined constructor, makes the idea impossible.
Arguably this is something that is permissible in the language, and that the warning should be tailored to permit. I don't think this falls afoul of any of the issues flagged in https://gcc.gnu.org/ml/gcc-patches/2017-06/msg01527.html for example. In the meantime, just explicitly zeroing the three member fields is easy and fixes the warnings.
