Jakob Stoklund Olesen 4bfc07ceb5 Tweak MachineLICM heuristics for cheap instructions. 
Allow cheap instructions to be hoisted if they are register pressure
neutral or better. This happens if the instruction is the last loop use
of another virtual register.

Only expensive instructions are allowed to increase loop register
pressure.
