I'll print a message when we skip an individual VL for this reason.
Note that it is hardware dependent what vector lengths exist in a system
and that it is expected that many possible vector lengths will be
skipped - the enumeration algorithm means that we don't explicitly step
through most vector lengths but rather have the enumeration done for us.

Please delete unneeded context from mails when replying.  Doing this
makes it much easier to find your reply in the message, helping ensure
it won't be missed by people scrolling through the irrelevant quoted
material.
