re PR middle-end/89998 (ICE: verify_gimple failed in printf-return-value)
PR tree-optimization/89998
* gimple-ssa-sprintf.c (try_substitute_return_value): Use lhs type
instead of integer_type_node if possible, don't add ranges if return
type is not compatible with int.
* gimple-fold.c (gimple_fold_builtin_sprintf,
gimple_fold_builtin_snprintf): Use lhs type instead of hardcoded
integer_type_node.
* gcc.c-torture/compile/pr89998-1.c: New test.
* gcc.c-torture/compile/pr89998-2.c: New test.
