I don't think this is correct.
The calling convention for 128-bit IEEE floating-point is *different* than the
calling convention for 128-bit IBM floating-point, so it's not enough to just
add to the test, you actually need to implement the IEEE calling convention!
While 128-bit IBM floating-point values are passed in a pair of floating-point
registers, 128-bit IEEE floating-point values are passed in a single vector
register.
