#5423: Registers above R8 corrupt when called through prim import

Comment(by ezyang):
At the very least the compiler should complain about foreign prims that
have too many arguments.
I think what we actually want here for the intended application (integer-
gmp style bindings) is some sort of facility for inlinable C--. In this
case, we can reuse the local registers that already hold all of these
values, for only a small code increase.
