beam_ssa_type: Track the types of tuple elements
Prior to 294d66a295f6c2101fe3c2da630979ad4e736c08 there wasn't much
point to keeping track of tuple element types; they were only known
when we had inserted or extracted values from a tuple, and in
neither case was it likely that we'd extract the same values again.
It makes a lot more sense to do so now that type optimizations are
applied across functions; if we return a tuple it's very likely
that its elements will be extracted soon after, and knowing their
types lets us eliminate more type checks.
