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

PR tree-optimization/31146
* tree-ssa-forwprop.c (forward_propagate_addr_expr_1): New
argument, single_use_p. If we have a single use that is
a conversion to the definition rhs type, propagate that rhs.
(forward_propagate_addr_expr): Pass single_use_p argument
to forward_propagate_addr_expr_1.
* g++.dg/tree-ssa/pr31146-2.C: New testcase.
