Fix return-type for PossibleInstructionResult of EnumInstructionResult

Fix unexpected return-type for `PossibleInstructionResult` of EnumInstructionResult

Added method `InstructionResults()` which returns the same data
as `PossibleInstructionResult()` but as an array.

Marked the `PossibleInstructionResult()` method as obulete, use
`InstructionResults()` instead.
