Reduce inlining in deeply-nested caseswip/T18730
This adds a new heuristic, controllable via two new flags to
better tune inlining behaviour.
The new flags are -funfolding-case-threshold and
-funfolding-case-scaling which are document both
in the user guide and in
Note [Avoid inlining into deeply nested cases].
