You can't do renames like this piece by piece. Every commit must build.

Incidentally, this is one of the reasons we often don't bother with
renames to follow spec changes, but rather stick to the original names.

However, in this case you could switch all drivers to the different test
pattern macros piece by piece, as they're already there.
