Generated reports are now correct and usable on unix and macos, but running cargo test with -Cinstrument-coverage on windows now fail:

process didn't exit successfully: `D:\a\diffutils\diffutils\target\debug\deps\diffutilslib-a04822fa61f6982e.exe` (exit code: 0xc0000005, STATUS_ACCESS_VIOLATION)

This requires further investigation, but the results on unix/macos are already quite promising.

Removing -Clink-dead-code from $RUSTFLAGS results in the tests passing on Windows.

This looks very similar to rust-lang/rust#76038. An old comment on that issue claims that:

-Clink-dead-code is no longer required or recommended when enabling coverage instrumentation

So let's just go with it!
