I suggest adding the following comment just before that type definition:

% This enumeration must be EXACTLY the same as the MR_PredFunc enum in
% runtime/mercury_stack_layout.h, and in the same order, since the code
% assumes the representation is the same.

Likewise, you should add a similar comment in runtime/mercury_stack_layout.h.

Apart from that, that change looks fine.
