to not drop optionals in memory all the time. We now generate a lot better code for them in many cases. This makes generated SIL more readable and should help -O0 perf. This is progress towards <rdar://problem/20642198> SILGen shouldn't be dropping optionals into memory all the time Swift SVN r28102
