* tree-flow.h (may_propagate_address_into_dereference): Declare.
* tree-ssa-ccp.c (may_propagate_address_into_dereference): New function.
(ccp_fold): Use it.
* tree-ssa-forwprop.c (rhs_to_tree): Remove useless conversions,
properly canonicalize binary ops.
(forward_propagate_addr_expr_1): Use
may_propagate_address_into_dereference.
