* tree-ssa-sccvn.c (visit_reference_op_load): If the lookup
found an expression with constants, note that in the VN for the lhs.
* tree-ssa-pre.c (eliminate): Visit COND_EXPR statements and
fold them to constants if possible. Run cleanup_cfg if done so.
(execute_pre): Return todo.
(do_pre): Likewise.
(execute_fre): Likewise.
* tree-ssa-forwprop.c (can_propagate_from): Allow propagation
of constants.
(get_prop_source_stmt): Look through pointer conversions.
* gcc.dg/tree-ssa/forwprop-4.c: New testcase.
* gcc.dg/tree-ssa/ssa-fre-16.c: Likewise.
