Silence overactive sanity check with -fpartial-profile-training

Browse Source 
do_estimate_edge_time tests that cached and real values matches. This test
is not working precisely for global profiles because of roundoff issues when
profile of clones is subtracted from profile of offline body.  This is checked
by presence of ipa counter. This breaks with partial profile training because
we turn IPA profiles to local when they drop to 0.

	* ipa-inline-analysis.c (do_estimate_edge_time): Silence overactive
	sanity check.
