llvm-cov: Move some reader debug output out of the tool.

Browse Source 
This debug output is really for testing CoverageMappingReader, not the
llvm-cov tool. Move it to where it can be more useful.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218183 91177308-0d34-0410-b5e6-96231b3b80d8
