why are we passing stdlib stuff as ffi?

Some of this is temporary, some is a quirk of embenchen.
I have another outstanding CL that stacks on the stdlib one to route stdlib
through to external functions prefixed with an underscore (as there are a few
places where that was already being done in embenchen).
I'll chat with ben tomorrow about doing opcodes vs ffi, as if we keep the ffi,
we'll have to have a second object for it.

NaN and Infinity are routed through ffi in embenchen which is another mismatch
with the spec.

Ah, just noticed this was missing the README I meant to include.
