Change llvm-cov output formatting to be more similar to gcov.
- Replaced tabs with proper padding - print() takes two arguments, which are the GCNO and GCDA filenames - Files are listed at the top of output, appended by line 0 - Stripped strings of trailing \0s - Removed last two lines of whitespace in output Patch by Yuchen Wu! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193148 91177308-0d34-0410-b5e6-96231b3b80d8
