Fix vec_cmp comparison mode
vec_cmps assign the result of a vector comparison to a mask.
The optab was called with the destination having mode mask_mode
but with the source (the comparison) having mode VOIDmode,
which led to invalid rtl if the source operand was used directly.

* optabs.c (vector_compare_rtx): Add a cmp_mode parameter
and use it in the final call to gen_rtx_fmt_ee.
(expand_vec_cond_expr): Update accordingly.
(expand_vec_cmp_expr): Likewise.
