Expand description

Loads an 8-bit value from `m` and sets lane `L` of `v` to that value.

This intrinsic is provided for completeness and is equivalent to `u8x16_replace_lane::<L>(v, *m)` (which doesn’t require `unsafe`).

## §Unsafety

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