It isn't LRA that doesn't scale, it is var-tracking memory clobbering that
needs improvements, but it would be nice to analyze what are the changes that
LRA does compared to reload that make var-tracking to take that much longer and
whether the generated code is better or worse.  If it is better, this is just
PR54402 dup.
