Tweak the HC_OPTS generation libraries/base/GHC/Base_HC_OPTS wasn't getting included, because we were using libraries/base/./GHC/Base.lhs as the path, and the ./ meant we got the wrong filename. I didn't use $(realpath ...) as the .hs file may be generated by hsc2hs or similar, so may not exist when the HC_OPTS are constructed.

Numerous small changes to the constraint solver The main thing is that we now keep unsolved Derived constraints in the wc_flats of a WantedConstraints, rather than discarding them each time. This actually fixes a poential (admittedly obscure) bug, when we currently discard a superclass constraint, and may never re-generate it, and may thereby miss a functional dependency. Instead, reportErrors filters out Derived constraints that we don't want to report. The other changes are all small refactorings following our walk-through.

Add a type signature for a function with an ambiguous type There's a comment with visit_PPSArgs to explain. GHC was rightfully rejecting visit_PPS as having an ambiguous type. And it does! It worked before because the ambiguity involved only standard classes and hence was resolved. (I suppose this could be a warning instead. But I'm fixing the test anyway.)

Don't report unused bindings of the form _ = e Thse are used in a few libraries, either to add type constraints via a signature, or to mention some variables that are only otherwise mentioned in one #ifdef branch
