Integrate LLVM@7a10fc8d542 (#23264)

Reverts carried forward:
* Local revert of https://github.com/llvm/llvm-project/pull/169614 due
to https://github.com/iree-org/iree/issues/22649

Other changes:
* cast shard.all_gather result type to `ShapedType` due to its result
changing types to be `AnyTypeOf<[AnyMemRef, AnyRankedTensor]>` in
https://github.com/llvm/llvm-project/pull/177202
