It's a bit of an odd one: The Haskell syntax

    foreign import prim "foo" ident :: type

is in principle portable, but whatever lies on the other side (some C--
code in the case of GHC) is almost certainly not.

Personally I'd have named it ForeignImportPrim, but I can also see the
logic behind making the name GHC-specific. I don't feel strongly either
way.

I think that ForeignImportGhcPrim is a better name than
GHCForeignImportPrim, though.
