I haven't started building the python bindings yet, so it won't currently work
with python.
I'm testing it against softfloat.
I put all the tests in the source code by using bash scripts to generate the
tests, since I want it to be testable without needing to build and properly
configure softfloat.
I am probably going to change the tests out for something else (maybe array
literals or data files) since they're currently 120kloc of function calls,
which takes quite a while to compile (5-10min).
