Kanghua Yu 86e68d02af [turbofan] Add verification for jump optimization. 
The jump optimization maybe run Turbofan pipeline twice for each TF/CS builtins,
and relies on the fact that the number of j/jmp instruction generated is always
the same.
This CL introduces a verification process to ensure that instruction sequence
and virtual registers are always the same in two stages, before the final
code generation phase.
