re PR tree-optimization/31146 (forwprop does not look through casts)

PR tree-optimization/31146
* tree-ssa-forwprop.c (forward_propagate_addr_expr_1): Restructure
to allow recursion of forward_propagate_addr_expr.
(forward_propagate_addr_into_variable_array_index): Likewise.
(forward_propagate_addr_expr): Likewise.
(tree_ssa_forward_propagate_single_use_vars): Likewise.
(forward_propagate_addr_expr_1): Recurse on simple copies
instead of propagating into them. Do so for useless conversions
as well.
(forward_propagate_addr_expr): Clean up unused statements after
recursion.
* g++.dg/tree-ssa/pr31146.C: New testcase.
