Rename float32/float64 to f32/f64. (#324)
* Rename `float32`/`float64` to `f32`/`f64`. The `float32` and `float64` types are being [renamed to `f32` and `f64`]. All the main tools have been updated to accept both old and new names for now, so there's no urgency to change anything, but users who wish to can now start switching to the new `f32`/`f64` names. [renamed to `f32` and `f64`]: #277 * Rename the Canonical ABI's `Float32`/`Float64` to `F32`/`F64`.
