llvm: fix lowering of non-byte-aligned field pointers
* When a field starts at some bit offset within a byte you need to load
starting from that byte and shift, not starting from the next byte,
so a rounded-down divide is required here, not a rounded-up one.
* Remove paragraph from doc that no longer relates to anything.
Closes #12363
