I guess this is cribbed from DXC, but do we really want these "ValidFlags"
entries in the enums? Who's going to use them? In general I feel like there are
better ways to validate that whatever flags we get match what we expect/can
handle, and adding extraneous values to enums makes things like
`-Wcovered-switch` less effective.
