So, it looks like GCC already uses `__builtin_clear_padding` and MSVC already uses `__builtin_zero_non_value_bits`. This patch (obviously) is currently implementing `__builtin_zero_non_value_bits ` but, I had planned to update it to use `__builtin_clear_padding`. Maybe that's not the best course of action, though.

We should all try to agree on _one_ name. CC @BillyONeal @jwakely thoughts?
