----------------
This will likely have to change when the wording is settled on for this
builtin. Namely, the element to insert is in BE word element 1 for the
instruction. So it is quite likely that the builtin will be made
"endianness-neutral" by specifying the source element to be word element 1 (for
both LE/BE).
