[PATCH v13 0/3] MR188: vkd3d-shader/tpf: Add support for emitting sample_l instructions
From what I can tell, the recent work on SampleBias/SampleLevel did all of the work for us, we just need to take the same framework and include the case for the `sample_l` instruction.
Tested with some shaders from the native Linux version of Little Racers STREET. -- v13: https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/188

The current revision at least gets sample_l to be as functional as sample_b, so maybe this commit needs to be a separate MR altogether? (Francisco will understand this patch better than me, so I'll defer to them for this one) -- https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/188#note_32394
