re PR middle-end/44203 (New prefetch test failures)

2010-05-25  Christian Borntraeger  <borntraeger@de.ibm.com>

PR 44203
* tree-ssa-loop-prefetch.c: Fix logic for step calculation to
match the original (and intended) behaviour before r159557.  This
changeset changed a=a+b*c to a=(a+b)*b which was obviously wrong
in two ways.
