I see something similar on x86_64-apple-darwin10, but with -fwhole-program and
not with -flto:
i.e., with -Ofast before or after r190346 the run time is ~150s and does not
change with -flto.
At r190345 and before, the run time with -fwhole-program is ~100s (and ~56s
with --param max-inline-insns-auto=98 -funroll-loops), while it is ~142s at
r190346 and after.
