/* Bases all the induction variables in LOOP on a single induction
variable (unsigned with base 0 and step 1), whose final value is
compared with *NIT. When the IV type precision has to be larger
than *NIT type precision, *NIT is converted to the larger type, the
conversion code is inserted before the loop, and *NIT is updated to
the new definition. When BUMP_IN_LATCH is true, the induction
variable is incremented in the loop latch, otherwise it is
incremented in the loop header. Return the induction variable that
was created. */
