OK. Nice work on getting this done, it is a big piece of work.

I have given it an update now that the baseline LLT changes are in-tree. A fair amount has changed since it was first written but I believe this is still doing OK. I have removed a lot of the actual BF16 code for the time being - I wanted to make sure that was checked properly as it was added and so can be added in stages. Things like loads and stores and calling conventions should work generically, as they should.
