Last time I checked on_load was unsupportable by HiPE.  The BEAM loader
did some hacks behind the scenes that it could get away with, but which
were unexpected by and incompatible with the HiPE loader.

Keeping HiPE and NIFs separate seems to be the only viable solution currently.

Alas there are effectively no compiler/vm developers left in the HiPE team;
we've all left to pursue other career paths.
