[transform] Better default tiles for small parallel dims - #305
Merged

Conversation
Extends default tile selection attempts to maximize vector register usage by pulling extra elements from outer dimensions if the innermost ones do not contain enough elements on their own. Default register unrolling mostly benefits from this change as other tiling steps need to use different heuristics to ensure good hardware utilization. Assisted-by: Claude
