I'm not sure there is a reasonable way other than experience and
intimate knowledge of how reload works.

I haven't done any measurements, but I see more questions/issues being
raised by developers doing their own ports with regards to reloading
than any other part of the compiler.

That's no great surprise, since reload is probably the nastiest pass of
the compiler and even those of us with significant experience still
struggle with corner case reload problems.
