Prior to this CL, collected shared function infos with identical
source ranges were sorted non-deterministically during coverage
collection. This lead to non-deterministically incorrectly-reported
coverage due to an optimization which depended on the sort order later
on.

With this CL, we now sort shared function infos by the source range
*and* call count.
