After a07b135ce0c0111bd83450b5dc29ef0381cdbc39, we always pass -coverage-notes-file/-coverage-data-file for driver options -ftest-coverage/-fprofile-arcs/--coverage. As a bonus, we can make the following simplification to cc1 options: * `-ftest-coverage -coverage-notes-file a.gcno` => `-coverage-notes-file a.gcno` * `-fprofile-arcs -coverage-data-file a.gcda` => `-coverage-data-file a.gcda` and remove EmitCovNotes/EmitCovArcs.
