* loop-doloop.c (doloop_valid_p): Rename to:
(validize_doloop). Try to fix up loops with conditons for infinite
looping by enclosing them in an outer loop.
Changed caller.
(add_test): Add new parameter

This sounds a bit similar to Nathan Froyd's recent work:

Sebastian Pop and I have been discussing the option of designing a new
pass, based on vrp, to normalize integer types towards a canonical
supertype typically a machine word, equivalent to signed long, or to
truncate to a smaller-size word when it makes sense. This would be a
very simple pass (o
