WIP: Add a nightly Hadrian/Darwin job
We mostly use the same settings as the make Darwin jobs. In particular, this becomes the only Hadrian job that tests the in-tree GMP configuration.
Marked WIP because:
- I put the job in the
build
stage instead offull-build
, for faster feedback in case I got it wrong. - I commented out the bits that tell GitLab this is a nightly job, in order to get the job to run in this MR, to see whether it works.
