For __builtin_ia32_vec_set_v16qi (a, -1, 2) with
!flag_signed_char. it's transformed to
__builtin_ia32_vec_set_v16qi (_4, 255, 2) in the gimple,
and expanded to (const_int 255) in the rtl. But for immediate_operand,
it expects (const_int 255) to be signed extended to
(const_int -1). The mismatch ca
