Improve type-error reporting
This patch does two things:
* When reporting a hole, we now include its kind if the
kind is not just '*'. This addresses Trac #14265
* When reporting things like "'a' is a rigid type varaible
bound by ...", this patch arranges to group the type variables
together, so we don't repeat the "bound by..." stuff endlessly
