Subject: [PATCH] warnings: Compiler warning on memset usage for non-trivial
 type

Problem:
- IS_TRIVIALLY_CONSTRUCTIBLE macro does not work correctly resulting
  in `memset()` usage to set a non-trivial type to 0 when
  `nontrivial_t` is passed in from the tests.
- Warning reported by GCC when compiling with `--enable-werror`.

Solution:
- Use the standard algorithm `std::fill_n()` and let the compiler
  determine the optimal way of looping or using `memset()`.
