Group the the code coverage, profiling, and pgo tests together (#16070)

* Group tests for profiling instrumentation together, NFC

This will make it easier to test changes to the code coverage logic.

There are a handful of tests which relate to profiling which I have not
moved. These include tests for the driver and for the SIL optimizer. It
makes more sense to keep those tests where they are.

* Rename a test file, NFC

This file tests code coverage of primary files, so I've changed the name
of the file to reflect that.

* Simplify the check lines in a test, NFC

This file tests code coverage of closures. It had several check lines
which obscured the meaning of the test, and its check lines were in a
strange order.

Remove the extra checks and disable -emit-sorted-sil.
