[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.
