Gurinder Singh c30e15aded Fail candidate assembly for erroneous types

Trait predicates for types which have errors may still
evaluate to OK leading to downstream ICEs. Now we return
a selection error for such types in candidate assembly and
thereby prevent such issues

README.md

This directory contains the test for incorrect usage of specialization that should lead to compile failure. Those tests break down into a few categories:

Feature gating
- On use of the default keyword
- On overlapping impls
Overlap checking with specialization enabled
- Basic overlap scenarios
  - Includes purely structural overlap
  - Includes purely trait-based overlap
  - Includes mix
- Overlap with differing polarity
Attempt to specialize without using default
Attempt to change impl polarity in a specialization
Attempt to rely on projection of a default type
- Rely on it externally in both generic and monomorphic contexts
- Rely on it both within an impl and outside it
