Move the operand iterator into MachineInstrBundle.h where it belongs.
Extract a base class and provide four specific sub-classes for iterating over const/non-const bundles/instructions. This eliminates the mystery bool constructor argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151684 91177308-0d34-0410-b5e6-96231b3b80d8
