[PATCH V4 1/3]rs6000: accurate num_insns_constant_gpr

Hi, Trunk gcc supports more constants to be built via two instructions: e.g. "li/lis; xori/xoris/rldicl/rldicr/rldic". And then num_insns_constant should also be updated. Function "rs6000_emit_set_long_const" is used to build complicated constants; and "num_insns_constant_gpr" is used to compute
