Separate out this change to a new patch please.

These changes are not related to ufs, so better keep all these in a separate
patch, say 'cleanup', as mentioned above.

So this changes and other vreg changes in cfg goes to the separate patch.

And these couple of changes too to the new patch. This helps in 
bisecting in the
time of issue.
