Generalize codegen and simplification of deopt.
Rationale: the de-opt instruction is very similar to an if,
so the existing assumption that it always has a
conditional "under the hood" is very unsafe, since
optimizations may have replaced conditionals with
actual values; this CL generalizes handling of deopt.
