Reland "More lazy deoptimization in Turbofan (binops, loads/stores)"
...
This relands commit r23029 + adds missing lazy deopts for JSAdd operator inside VisitForInStatement. The added lazy deopt still refers to a bogus bailout id, but at least the graphs can be scheduled.

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.
