[FIR] Additional errors to distinguish resolution to classifier cases

When a call is resolved to a classifier, only a single error message was
being used for multiple cases. This lead to confusion as the default
message may not be applicable to a given error case. Added additional
errors and messages to distinguish between these error cases.
