target/ppc: Move cmp{rb, eqb}, tw[i], td[i], isel instructions to decodetree.
Moving the following instructions to decodetree specification :
cmp{rb, eqb}, t{w, d} : X-form
t{w, d}i : D-form
isel : A-form
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 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 required
bits using offsets (tcg_gen_extract_i32).
