205085d8d5 8223138: Small clean-up in loop-tree support
Rename predicate 'is_inner()' to 'is_innermost()' to be accurate. Added 'is_root()' predicate for root parent test in loop-tree. Changed definition of 'is_loop()' to always lazy-read the tail, since it should never be NULL. Cleanup of 'tail()' definition.
