Undo unnecessary changes.

We found a bug when we enable shrink-wrapping + SCO, and do llvm bootstrap testing.
After we dig into the bug, we think it's **NOT** SCO's issue, we have tested disable shrink-wrapping, this patch can pass bootstrap testing, spec2006 testing.

The bug is, in some cases, shrink-wrapping + SCO will cause the tail call branch disappear, we don't know why and we are investigating it.
