poly_int: expand_expr_real_1
This patch makes the VIEW_CONVERT_EXPR handling in expand_expr_real_1
cope with polynomial type and mode sizes.

* expr.c (expand_expr_real_1): Use tree_to_poly_uint64
instead of int_size_in_bytes when handling VIEW_CONVERT_EXPRs
via stack temporaries. Treat the mode size as polynomial too.
