d04a7d6d91 More lazy deoptimization in Turbofan (binops, loads/stores) 
Deoptimizing binory operations, (Load|Store)(Property|Named),
constructors.

This also fixes safepoint lookup to account for lazily deoptimized code.

670df5063b Implement representation selection as part of SimplifiedLowering. Representation selection also 
requires inserting explicit representation change nodes to be inserted in the graph. Such nodes
are pure, but also need to be lowered to machine operators. They need to be scheduled first, to
determine the control input for any branches inside.

This CL requires extensive testing. More tests to follow.
