Are there other intrinsics like _mm_maskmoveu_si128 that require mutable memory even when no mutation occurs?

Description
As documented in https://github.com/rust-lang/stdarch/pull/2196, _mm_maskmoveu_si128(a, mask, ptr) requires the memory ptr points to to be writable, even if the mask makes it so that no write actually occurs.
Are there any other intrinsics like that? They should all get corresponding remarks in their documentation.

Research direction
Start by reviewing stdarch PR 2196 and the documentation for _mm_maskmoveu_si128, then search the intrinsic documentation for other operations whose memory must be writable even when no write occurs. Done means identifying every matching intrinsic and adding a corresponding documentation remark for each.
