[Patch,optimization]: Optimized changes in the estimate register pressure cost.

,optimization]: Optimized changes in the estimate register pressure cost. Earlier the estimate_reg_pressure cost uses the cost of n_new variables that are generated by the Loop Invariant and IVOPTS. These are not sufficient for register pressure calculation. The register pressure cost calculation should
