Previously, error types on those implicit parameters were being lost.
Changed test data is only partly here
(only parts that are considered to be correct).
Other ones (new green-to-red changes) should belong to the next commit
and will be fixed soon (as a part of PCLA).
Several tests are affected by the usage of fixation direction calculator in FIR.
Restored to mimimize test data changes.
It is unnecessary in FE10 because a type variable with unknown type
is inferred into an error type, but affects test data in FIR where
Nothing/Any is selected by direction (as a temporary measure).
CR candidate in spec test is Unresolved in FIR because top-level CRs are resolved as call arguments.
Resolution ambiguity is also present in FE10 when CR is wrapped into an id call.
