jumper, kill off F4

Its alignment (sometimes 4, sometimes 16) has proven to be error-prone.

This also means we don't really need LazyCtx::load().

I think I only had it there to make sure we were doing unaligned loads
of F4; the better way is to just never declare the data as aligned...

The generated code isn't quite as good, but I can live with it.
