  Log Message:
  -----------
  [llvm-cov gcov] Don't suppress .gcov output if .gcda is corrupted

If .gcda is corrupted, gcov continues to produce a .gcov and just
assumes execution counts are zeros. This is reasonable, because the
program can corrupt its .gcda output. The code path should be similar to
the code path without .gcda.
