llvm-cov: Support gcov's extermely lenient treatment of -o

Programming / Compilers / LLVM - Justin Bogner [justinbogner.com] - 18 February 2014 03:19 UTC

In gcov, the -o flag can accept either a directory or a file name. When given a directory, the gcda and gcno files are expected to be in that directory. When given a file, the gcda and gcno files are expected to be named based on the stem of that file. Non-existent paths are treated as files.

This implements compatible behaviour.
