Peter Collingbourne 718dba15cd ModuleUtils: Stop using comdat members to generate unique module ids.
It is possible for two modules to define the same set of external
symbols without causing a duplicate symbol error at link time,
as long as each of the symbols is a comdat member. So we cannot
use them as part of a unique id for the module.
