76bf991538 Reapply (2x) "[PGO] Fix name encoding for ObjC-like functions"
Function names in ObjC can have spaces in them. This interacts poorly
with name compression, which uses spaces to separate PGO names. Fix the
issue by using a different separator and update a test.

I chose "\01" as the separator because 1) it's non-printable, 2) we
strip it from PGO names, and 3) it's the next natural choice once "\00"
is discarded (that one's overloaded).

What's changed since the original commit?

- I fixed up the covmap-V2 binary format tests using a linux VM.
- I weakened the CHECK lines in instrprof-comdat.h to account for the
  fact that there have been bugfixes to clang coverage. These will be
  fixed up in a follow-up.
- I added an assert to make sure we don't get bitten by this again.
- I constructed the c-general.profraw file without name compression
  enabled to appease some bots.

8824b89ee3 [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.
