target-i386: compute eflags outside rcl/rcr helper
Always compute EFLAGS first since it is needed whenever the shift is non-zero, i.e. most of the time. This makes it possible to remove some writes of CC_OP_EFLAGS to cpu_cc_op and more importantly removes cases where s->cc_op becomes CC_OP_DYNAMIC. Also, we can remove cc_tmp and just modify cc_src from within the helper. Finally, always follow gen_compute_eflags(cpu_cc_src) by setting s->cc_op and discarding cpu_cc_dst.
