Update per-file selftest and finalization hooks for .c to .cc renaming

This is mostly a mechanical change, apart from:
- fix the name of attribute_c_tests to match its filename (attribs.cc)
- fix the name of opt_proposer_c to match its filename (opt-suggestions.cc)
- delete a bogus "modref_c_tests" decl from ipa-modref-tree.h that's been
  present since the initial commit of that file
  (d119f34c)
