[llvm-cov] Use the native path in the coverage report.
The coverage reports contain the source or binary file paths. On Windows,
the file path might contain the seperators of both '/' and '\'. This patch
uses the native path in the coverage reports. For example, on Windows,
all '/' are converted to '\'.
