This seems to be the least disruptive to existing developers while
maintaining the invariant we want. It has the advantage of potentially
being extended in the future to add additional criteria for merges
(e.g. "it builds" or "it passes this set of tests").

To me this is the least desirable. I'd prefer we have one way of
getting changes into the repository.

I am completely fine with this. It's friendlier to new contributors.
That said, I assume with #1 we wouldn't prevent users from git push-ing
their local branch to GitHub (i.e. not using git llvm push) and manually
opening a PR, so either #1 or #3 works for new developers.

Maybe a slight preference for #1 as being less disruptive than #3 but I
really don't care either way.
