cfg: add missing REPEAT_CFG_CLEANUP
simplify_branch() & insert_branch() convert a conditional branch
into an unconditional one, removing a child which may then
become unreachable.
However, these function doesn't set REPEAT_CFG_CLEANUP and the
unreachable child may not be removed.
Fix this by setting the missing REPEAT_CFG_CLEANUP in these functions.
