Simplify key EnableDeSSAAlias

Browse Source 
EnableDeSSAAlias is of int originally during development of coalescing
alias (bitcast, etc) to have a finer control. It is stable now and no
longer need to be of int.

This submit has the following changes:
   1. Changes EnableDeSSAAlias to bool;
   2. Change DisableDeSSA to EnableDeSSA
   3. Guard the use of EnableDeSSAAlias with EnableDeSSA as EnableDeSSAAlias
      is used only if DeSSA is on.

No function change expected from this submit.
