Moving the following instructions to decodetree specification : {l, st}xvl(l) : X-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 added a new function do_ea_calc_ra to calculate the effective address : EA <- (RA == 0) ? 0 : GPR[RA], which is now used by the above-said insns, and shall be used later by (p){lx, stx}vp insns.
