Roll forward: lower cumulative reductions to chlo.ScanOp on TPU
Roll forward: lower cumulative reductions to chlo.ScanOp on TPU
Relands the chlo.ScanOp lowering of cumsum, cumprod, cummax and cummin
on TPU. The downstream issues behind the rollback are fixed. Export mode
and libtpu versions older than 0.0.51 keep the reduce_window lowering;
that guard can be removed after 2026-11-21.
PR was closed without comments.
