Diego Novillo b72f3e0d32 Final fix for PR 23499 and IR test case.
This fixes a bit I forgot in r238335. In addition to the data record and
the counter, we can also move the name of the counter to the comdat for
the associated function.

I'm also adding an IR test case to check that these three elements are
placed in the proper comdat.
