The spec still uses the DDI C-F names on icl for the TC DDIs.
My idea here is to match the spec terminology.
However, it's going to get annoying in the future because some
of the TC DDIs revert back to alphabetic names in the future,
and in a way that doesn't match the original alphabetic names.
Not quite sure how to deal with that. Probably more aliases,
but this time with a platform specific suffix :(
