PR middle-end/64715
* tree-chrec.c (chrec_fold_poly_cst): Use useless_type_conversion_p
for type comparison and gcc_checking_assert.
(chrec_fold_plus_poly_poly): Likewise.
(chrec_fold_multiply_poly_poly): Likewise.
(chrec_convert_1): Likewise.
* gimplify.c (gimplify_expr): Remove premature folding of
&X + CST to &MEM[&X, CST].
* gcc.dg/pr15347.c: Use -O.
* c-c++-common/pr19807-1.c: Likewise.
