Extended Description

When list-ilp was enabled by default on 2011-03-07, MultiSource/Benchmarks/MiBench/telecomm-gsm slowed down by 30% vs. list-burr (it now takes 40% more time to execute). The same regression occured in my own tests and in the x86_64 nightly builder. The i386 nightly builder reported no change.
