Clean up "pattern doesn't bind x" messages
Group "missing variable bind" spans in `or` matches and clarify wording
for the two possible cases: when a variable from the first pattern is
not in any of the subsequent patterns, and when a variable in any of the
other patterns is not in the first one.

* Check inconsistent bindings in all arms
* Simplify wording of diagnostic message
