Implement tagToEnum# for the bytecode system. Blargh. We spot tail-calls tagToEnum# <type> arg and emit code to push the arg, then do a bytecode test-sequence to determine what value it is, push the relevant constructor, and merge control flow again, at a label which does the normal tail-call sequence: slide the constructor down to the sequel and enter it. Blargyle, or as some would say, barferama.
