Replace mode_for_int_vector with related_int_vector_mode
mode_for_int_vector, like mode_for_vector, can sometimes return
an integer mode or an unsupported vector mode. But no callers
are interested in that case, and only want supported vector modes.
This patch therefore replaces mode_for_int_vector with
related_int_vector_mode, which gives the target a chance to pick
its preferred vector mode for the given element mode and size.
