The changes were verified by validating that the tcg ops generated by those instructions remain the same, which were captured using the '-d in_asm,op' = flag. Also, remaned do_divwe method in fixedpoint-impl.c.inc to do_dive because i= t is now used to divide doubleword operands as well, and not just words.

Also for CMPRB, following review comments : Replaced repetition of arithmetic right shifting (tcg_gen_shri_i32) followed by extraction of last 8 bits (tcg_gen_ext8u_i32) with extraction of the req= uired bits using offsets (tcg_gen_extract_i32).
