Every generic machine instruction must have generic virtual registers only, that is, have a low-level type attached to each operand. Previously MachineVerifier would catch a type missing on an operand only if the previous operand for the the same type index exists and have a type attached to it and it will report it as a type mismatch. This is incosistent behaviour and a misleading error message. This commit makes sure MachineVerifier explicitly checks that the types are there for every operand and if not provides a straightforward error message.
