* loop.c (strength_reduce): If scan_start points to the loop exit
test, be wary of subversive use of gotos inside expression statements.
Don't set maybe_multiple for a backward jump that does not
include the label under consideration into its range.
* unroll.c (biv_total_increment): Make use of maybe_multiple field.
