Revision 122896, more specifically the change in tree-scalar-evolution.c,
causes a regression on bfin-elf when compiling libiberty's hashtab.c. This
change eliminated a piece of code that examined the cost of a change before
modifying the code. As a result, there are now additional (expensive) division
operations in the generated code for hashtab.c, while no divide appears in the
source code.
