d: RHS value lost when a target_expr modifies LHS in a cond_expr
To prevent the RHS of an assignment modifying the LHS before the assignment proper, a target_expr is forced so that function calls that return with slot optimization modify the temporary instead. This did not work for conditional expressions however, to give one example. So now the RHS is always forced to a temporary. PR d/101282 gcc/d/ChangeLog: * d-codegen.cc (build_assign): Force target_expr on RHS for non-POD assignment expressions. gcc/testsuite/ChangeLog: * gdc.dg/torture/pr101282.d: New test.
