Make jit/notes.txt better reflect current status quo
gcc/jit/ChangeLog:
* notes.txt: Show the beginning and ending of
recording::context::compile vs playback::context::compile. Show
the creation and unlinking of the tempdir. Show toplev::finalize.
Move "RELEASE MUTEX" to the correct location. Show
gcc_jit_result_release, and indicate where the
dlopen/dlsym/dlclose occur.
