Only one of the optimizatons performed by the strength reduction pass
was disabled. However some people say that few CPUs with just a few
registers shouldn't use that optimization anyway as it tends to produce
slower code, so -fno-strength-reduce is a good thing anyway. And
to my knowledge the particular optimizer bug doesn't show up for
other architectures.

Like 2.7.2.1.
