first release of pa_ppx_migrate_ocaml_parsetree, 0.01

[chetmurthy]

This is broken out of pa_ppx_migrate (to make that build much faster), provides migrations between ocaml 4.02.0 <-> 5.3.0 and all intermediate versions.

[chetmurthy]

There are two failures, both due to mangled object-files produced by compile-steps. I took the docker script for the "4.12" build, and ran it myself locally. I found that it would sometimes go thru and sometimes fail. I'm going to "rebuild failed" and see if after a few tries, things go thru, but at this point, I don't think the problem is with the actual CI run.

Do you want to investigate this further?

[chetmurthy]

It's a little difficult to investigate, b/c it takes so long to run the test (even on my local Radeon server). I -did- do some investigation. I found that splitting the install into "deps-only" and then "the package" made the failure go away. But as I noted above, even the original Docker script sometimes succeeds on my local machine (though never, so far, on the CI cluster).

OK, all the tests passed. I'm glad you pushed me about what I thought was a build-system glitch. It was in fact a bug in my Makefile that only showed up under a poorly-timed race condition. But fixed now.

Thanks for the patience!
