* tree-cfgcleanup. (cleanup_control_expr_graph) <GIMPLE_COND>: Remove
code doing propagation from degenerate PHI nodes.
* tree-ssa-loop-ivcanon.c (propagate_into_all_uses): New function.
(propagate_constants_for_unrolling): Likewise.
(tree_unroll_loops_completely): If the current loop has been unrolled
and its father isn't the entire function, propagate constants within
the new basic blocks by means of propagate_constants_for_unrolling.
