Avoid emitting unnecessary write barriers for PutByVal and PutPrivateName

Summary
Avoid emitting unnecessary write barriers for PutByVal and PutPrivateName

This bug would disclose a security issue, and so I chose to also categorize it as security. We should avoid emitting write barriers when they are not needed, for example when we do not touch the butterfly. An example of this is a PutPrivateName that is not a define and has a non-cell value. See DFGStoreBarrierInsertionPhase FIXMEs for PutByVal and PutPrivateName.
