Compensate in compiler for verifier shortcomings.
The verifier does not differentiate zero and null, so a move-object
of zero can be used as a non-object later on.
Change the compiler to ignore the object conversion when the input
is zero or a phi (which might just hold zeros). The type propagation
will then do proper inferencing of the types.
Also remove some stalled comments in ssa_builder.cc.
