I've got bootstrap both with and without checking on IA-64 without any
problems.  It looks like there is some bug appearing and disappearing
since Diego's SPEC95 tester is logging misscompares for over a month.
It would be nice to know a bit more about the failure, but if we can't
get around it, perhaps reverting the patch is easiest solution - there
are other low hanging fruits on the testcase memory footprint and this
code is probably going to disappear with dataflow branch merge.
