The intent of ": 1" is to use individual bits to store the bool state of
these class values. Because true != 0, this worked. But it was likely to
bite someone sometime. (My bad: 0fe17e22f6.)
This commit also adds m_accepts_optional_like_value to the bit field and
sets the default false value in the constructor.
Because we cannot set a default value during declaration (until C++20).
make sure future coders know to set the preferred default in the
constructor.

implemented as constexpr in the relevant libc++.
