Actually, I wonder whether Daniel Berlin work will magically help? In 
my  very rough, current understanding, should exactly help with unused 
members of structures and the related loads and stores, well beyond 
SRA... I will try to understand those things in better detail and I'd 
like to ask Chris to do the same: at least monitor the generated 
assembly until after Danny work goes in.
