There was another discussion with David Chisnall, where he gave a good
overall on some of the complications for doing so:

should be enough tests in Clang to that effect.

For now, I just want to make sure it works on ARM/AArch64, even if I
have to hack my way through it. If I can have at least a buildbot
testing them, we'll be sure not to regress in functionality. System
integration is a secondary issue.
