  "message": "Remove the patterns that create dispatch regions without tile+fuse+distribute. (#7328)\n\nWith TiledOpInterface most of the operations to be executed on the\r\ndevice can be tiled and distributed. So the pattern that created a\r\nnon-tiled and distributed dispatch region can be removed.\r\nSimplify the code that decides which ops are root ops.\r\n\r\nTo make all tests pass, the last operation that needs to be tiled and\r\ndistributed is tensor.extract_slice. Add an external model to\r\nimplement the tile+distribute of this op to allow deleting the fall\r\nback path.\r\n\r\nThis is recommit of PR #7306 which was reverted in #7319 due to failure\r\non integrate. The changes from #7306 fix the breakages.\r\n\r\nResolve tensor.dim operation before legalization during dispatch\r\nregion formation.\r\nAllow tiling of tensor.extract_slice with non-unit strides.",
