Fix overflow check in profile_count::operator* (const sreal &num).

[Jan Hubicka]

Hi,
this fixes stupid mistake of mine in the overflow check for sreal
multiplication.  This was introduced this stage1 so unless we want to
backport the ipa-cp heuristics bugfixes, this does not need to go to
release branches.

Regtested and bootstrapped x86_64-linux.
