Gfx11-12 can support SLM block loads via OWord Block Load messages (notably, the aligned version, not the unaligned version). A while back we deleted the SHADER_OPCODE_OWORD_BLOCK_READ opcode. Rather than bring it back, we continue using UNALIGNED_OWORD_BLOCK_READ for SLM block access (like we do for SSBOs) but switch it over to the aligned variant when lowering logical sends. We do ensure the alignment is at least 16B, however. This is ugly, but it's probably not worth bringing back a whole extra opcode for a legacy HDC block load quirk.
