Try the attached patch on your homebrew setup.

This compiles and passes "make check", though I do not think it runs any jit tests.
So intead I dropped this into my 17.6, disabled the __arch64__ guard to make sure
I get the backport class, rebuilt and ran the jit on/off example from the docs.
This showed the expected performance difference with jit=on vs. off.
