Make llvm-cov compatible with gcov for cases where multiple files are specified on the command line. That is, loop over each one and report coverage, and report errors on stderr only rather than via return code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211959 91177308-0d34-0410-b5e6-96231b3b80d8
