[Mlir-commits] [mlir] [mlir][gpu] Add `subgroup_broadcast` op (PR #152808)

[Krzysztof Drewniak]

Approved since the op seems fine, but we'll want to make sure that lowering doesn't cause problems - possibly in a followup PR

(Side note, also for a future PR, this operation can implement the two integer bounds interfaces by just passing through the range of the input)
