Detailed Description
Return from a function with a value.
This opcode causes the virtual machine to exit from the current function and return to the caller, supplying the value given. The value given in the return is expected to be the same type as the function's return-value.
This operand must be the last opcode in a basic block because it terminates the execution of that block and no further operations will be executed in that block. Any operations after a jump will be considered 'unreachable' and may trigger a compile error or dropped with a warning.

Produce a description of the operation.
This method returns a full description of the operation including the return-value, operands, and any other ancilary information about the operation. This is a string that is constructed dynamically when needed and is used almost exclusively by the "dump" method to provide debuginng information.
Reimplemented from Gyoji::mir::Operation.
