[Coverage] Add a test case for comdat

The binary contains two (merged) covmap sections which
have duplicate CovMapRecords from comdat (template instantation).
This test makes sure the reader reads it properly. It also
tests that the coverage data from different instantiations
of the same template function are properly merged in show
output.
