  Changed paths:

    M compiler-rt/test/sanitizer_common/TestCases/sanitizer_coverage_inline8bit_counter_default_impl.cpp

  Log Message:
  -----------
  [sanitizer coverage] write the pc-table at the process exit

The current code writes the pc-table at the process startup,
which may happen before the common_flags() are initialized.
Move writing to the process end.
This is consistent with how we write the counters and avoids the problem with the uninitalized flags.
Add prints if verbosity>=1.
