Subject: [PATCH] Use `OutputFilenames` to generate output file for
 `-Zllvm-time-trace`

The resulting profile will include the crate name and will be stored in
the `--out-dir` directory.

This implementation makes it convenient to use LLVM time trace together
with cargo, in the contrast to the previous implementation which would
overwrite profiles or store them in `.cargo/registry/..`.
