Justin Bogner c92330c18c llvm-cov: Handle missing source files as GCOV does
If the source files referenced by a gcno file are missing, gcov
outputs a coverage file where every line is simply /*EOF*/.  This also
occurs for lines in the coverage that are past the end of a file that
is found.

This change mimics gcov.

These inputs were pre-generated to allow for easier testing of llvm-cov.

test.gcno and test.gcda were create by running clang:
  clang++ -g -ftest-coverage -fprofile-arcs test.cpp

test.cpp.gcov was created by running gcov 4.2.1:
  gcov test.cpp
