[PATCH] Fix profile count comparison.

[Eugene Rozenfeld <Eugene.Rozenfeld@microsoft.com>]

The comparison was incorrect when the counts weren't PRECISE.
For example, crossmodule-indir-call-topn-1.c was failing
with AutoFDO: when count_sum is 0 with quality AFDO,
count_sum > profile_count::zero() evaluates to true. Taking that
branch then leads to an assert in the call to to_sreal().

Tested on x86_64-pc-linux-gnu.

gcc/ChangeLog:

        * ipa-cp.cc (good_cloning_opportunity_p): Fix profile count comparison.
