Update some comm counts

Update comm counts for:
 - distributions/robust/arithmetic/performance/multilocale/alloc
 - distributions/robust/arithmetic/performance/multilocale/alloc_all

This updates the comm counts for most distributions for these tests as they
improved with the updates to licm. Note that alloc_all.replicated did not seem
to change, but I didn't investigate at all.
Remote list of current failures
Clean up licm.

Now that licm has been moved before insertWideReferences, there's no reason to
check for wide things.

I also updated how to check if a variable is passed by reference and added a
better comment to it.
Update compiler perfkey order to reflect licm being moved
Update lots of comm counts for the better!
