We predict main() as executed once, not cold, so code inside loop is inlined
for speed at -O1/-O2/-O3, but this testcase is compiled with -Os.

This seems like usual problem with comdat functions being possibly shared with
other compilation units.  I will check how -fwhole-program behaves and if I can
do something with the heruistics here.
