[Bug optimization/14046] [tree-ssa regression] address calculation not moved out of innermost loop

looking at the loop optimizer dump and comparing to 3.4, I see that for tree-ssa:

Loop at 71 ignored due to multiple entry points.

so the tree optimizers obfuscate the loop too much it seems (in fact, the
optimized tree dump looks very obfuscated - to me ;) ).

I remember a patch floating around to avoid the obfuscation, but don't remember
if it was applied. Jeff?
