Reid Kleckner bb55f795cb [IPSCCP] do not break musttail invariant (PR36485) ...

Do not replace results of `musttail` calls with a constant if the
call itself can't be removed.

Do not zap returns of `musttail` callees, if the call site can't be
removed and replaced with a constant.

Do not zap returns of `musttail`-calling blocks, this breaks
invariant too.
