Fix early inliner ICE

Fix early inliner ICE

[Jan Hubicka]

Hi,
in previous patch I mistakely comitted testcase for 40556 that is fixed by this patch.
Problem is that loop doing incremental inlining for fixed number of iterations has
wrong exit condition so we decide on inlining but do not apply in last iteration.

Bootstrapped/regtested x86_64-linux.  I will also update PR info of the previous commit
while comitting this.

	PR tree-optimize/40556
