[PATCH] c-family: Tighten vector handling in type_for_mode [PR94072]

In this PR we had a 512-bit VECTOR_TYPE whose mode is XImode (an integer mode used for four 128-bit vectors). When trying to expand a zero constant for it, we hit code in expand_expr_real_1 that tries to use the associated integer type instead. The code used type_for_mode (XImode, 1) to get this
