When we're comparing a zero-extended variable against a constant integer, we can bypass the `zext` if the constant fits into the narrower width. This isn't always a win (sometimes we want the `zext` value for other purposes), but it wins more often than it loses. Several existing tests have to be changed because they are now more fully optimised.
