Swift style syntax

My operator names for the shifts were modeled after the typical assembly
- `<<` - `shl` (logical left shift)
- `>>` - `sar` (arithmetic/sign propagating right shift)
- `>>>` - `shr` (logical right shift)
There is no arithmetic left shift, since it's effectively equivalent to the
logical version IIRC.
My main wish is that the names should be short, or there would be no
advantage of using them.
