This commit just introduces the instruction. In a subsequent commit, I am going to add support to SILGen to emit this. This ensures that when we assign into a tuple var we initialize it with one instruction instead of doing it in pieces. The problem with doing it in pieces is that when one is emitting diagnostics it looks semantically like SILGen actually is emitting code for initializing in pieces which could be an error.
