Previously, type arguments could only be inferred for generic
functions in call expressions, whereas with the reverse type inference
proposal they can now be inferred in assignment contexts too. As a
consequence, we now need to check Info.Instances to find the inferred
type for more cases now.
Updates #59338.
Fixes#59955.
