Also happens at rev. 155544 on x86_64-unknown-linux-gnu, with both -m32 and
-m64. "-O3 -floop-block" gives different results than "-O3" alone (and is much
faster). Profiling should indicate what part of code is different (I tried
diff'ing the optimized tree dumps, but it's too hard with the variable name
changes).
