nit: We're passing a double into the intrinsic in this test. I think the name of this test might sound a bit too similar to the other one (`test_lroundf32`). Maybe we should update this to indicate something like f64 (but returning an i32)?

Anyway, this is just a picky nit of mine but if you don't feel it is necessary you can feel free to disregard.
