target/sh4: move DELAY_SLOT_TRUE flag into a separate global
Instead of using one bit of the env flags to store the condition of the
next delay slot, use a separate global. It simplifies reading and
writing the flags variable and also removes some confusion between
ctx->envflags and env->flags.
Note that the global is first transfered to a temp in order to be
able to discard the global before the brcond.
