I did use `llvm/utils/update_llc_test_checks.py` to generate the CHECK lines, but I reverted the hunks that just reordered the CHECK lines in the existing tests as I thought this would just add noise in the PR. I can reorder these if you like, though.

You're right, though, I should have precommihted the tests. Good spot 😅
