thanks !

I think we should revert this change because:

• It broke support for command lines that contain any other -Z flag
• It broke support for -Zprofile, which may still be used with older version of rustc
• It tracks a profraw file that is irrelevant: it would be the equivalent to gcda, not gcno. And actually it never exists, because even when the program is run and a profraw file is generated, its name is different.

Hi, I reviewed all the documentation for Instrumentation-based Code Coverage and Profile-guided Optimization and now understand the mistake pointed out by @glandium. (Thank you for that!) I’m currently working on it and will restore everything back to normal.
