Strictly speaking, this is not necessary for .cpp files. However, other .cpp
files from this same tool have it. This also matches what we do in other tools.

Summary:
This patch eliminates many places where we originally needed to pass index
values to represent an instruction. The index is still used as a key, in various parts of
MCA. I'm not comfortable eliminating the index just yet. By burying the index in
the instruction, we can avoid exposing that value in many places.
Eventually, we should consider removing the Instructions list in the Backend
all together, it's only used to hold and reclaim the memory for the allocated
Instruction instances. Instead we could pass around a smart pointer. But that's
a separate discussion/patch.

The logic remains the same. Eventually, I see the RCU acting as its own separate stage in the instruction pipeline.
