Expand description

Load four 16-bit integers and sign extend each one to a 32-bit lane

## §Unsafety

This intrinsic is unsafe because it takes a raw pointer as an argument, and the pointer must be valid to load 8 bytes from. Note that there is no alignment requirement on this pointer since this intrinsic performs a 1-aligned load.
