Subject: iris: Re-enable param compaction

iris: Re-enable param compaction

In d1c4e64a69e, we added a parameter to tell the back-end compiler to
ignore the param array and just push however many constants you ask it
to push.  I enabled it for iris because this is really what iris wants
but it seems to have caused a number of regressions.  Revert to the old
behavior for now.

Fixes: d1c4e64a69e "intel/compiler: Add a flag to avoid compacting..."
