[PATCH] vect: Fix ICE in vect_analyze_loop_costing [PR113210]

Hi! The following testcase ICEs (on ARM/RISCV with certain options), because niters analysis computes number of latch executions for the loop as (short unsigned int) (a.0_1 + 255) + 1 > 256 ? ~(short unsigned int) (a.0_1 + 255) : 0 where a.0_1 is unsigned char. This is correct, but given that
