I double checked what's going on and the successors of the block have been swapped, but the names for the patterns for the blocks haven't been updated automatically (only where they have been used). Updated the pattern names. There's still a change from `ult` to `ule`, which is due to us now vectorizing with interleave groups, which requires the scalar epilogue to execute at least once.
