Currently, some instructions will be missing from the list of ordered_instructions. This will cause issues due to the debug change which passed the last instruction into subsequent passes. This CL moves the addition to the ordered list out of the RegisterInstruction method into AddOrderedInstruction. This method is called first in ProcessInstruction and the CapabilitiesPass and IdPass are updated to take an Instruction parameter.
