@eduardosm can you split off the library parts into their own PR? |

It's not obvious that these are all harmless changes - sometimes the explicit return expresses intent, so it should be preserved to account for future possible refactorings even if it does not make a difference right now.

I undid some of the changes, trying to keep only the most obvious ones. |

IMO it is nicer, for symmetry with the return just a few lines above, to use return here.
That's exactly why I don't like just forcing such clippy lints over the entire codebase...

I have exactly the opposite opinion. I like the consistency that tools like clippy encourage, and in this case I think the change makes the "early return" and "default/fallthrough" visually distinct, which I find easier to read.

The last two returns here are not distinct in a meaningful sense, so it is not a good idea to make them visually distinct.

I agree with @saethlin. I think it's just plain odd to have return value; at the end of a block when it's not suggesting exceptional control flow.
I think it's actually very odd that miri has allow(clippy::needless_return) on its codebase, but for the rest of the compiler I think this should be fixed.

I ended up implementing the exact same changes, so I basically did a complete review of this by doing the changes myself. This LGTM.
