Title: SI-6221 inference with Function1 subtypes.

There appears to be no upper bound on the number of places we have to remove
calls to typeSymbol and introduce calls to baseType. This one was type
inference for function parameter types: worked when expected type was A => B,
but not if there was an implicit conversion from A => B to the expected type.
