* Rejig the error messages a bit; fixes a minor bug
The type checker was only reporting the first message if an equality
failed to match. This patch does a bit of refactoring and fixes the
bug, which was in the bogus use of eqInstMisMatch
in tcSimplify.report_no_instances.b
This is really a bug in 6.8 too, so this would be good to merge across
to the 6.8 branch.
