regress/script-tests/deltablue-varargs.js.ftl-no-cjit-no-put-stack-validate on FTL B3 gets a B3 validation failure

Reviewed by Geoffrey Garen and Saam Barati.
It turns out that the FTL was creating orphans. Rather than making the FTL handle them by
itself, I gave B3 the power to eliminate them for you. I also made the dumper print them
since otherwise, you wouldn't know anything about the orphan when looking at a validation
failure or other kind of procedure dump.
