Alexander Belyaev d4f2c767d3 [HLO] Fix HLO DynamicBroadcastInDimOp -> LHLO lowering.
The conversion had a bug in computation of strides and sizes args for std.memref_reinterpret_cast. The previous version also relied on linalg::ReshapeOp to do broadcasting when the rank of the output was higher than the rank of the input. Now the broadcasting is entirely done via descriptor modification and linalg::ReshapeOp was replaced with CopyOp.

Ehsan Toosi d599485e06 PR #43069: [hlo] Unbreak hlo-legalize-to-lhlo test
Imported from GitHub PR https://github.com/tensorflow/tensorflow/pull/43069

The legalization of mlhlo.ReturnOp to lhlo.TerminatorOp by using BufferAssignmentReturnOpConverter fails since the Memref typed results (or the Memref typed operands of Return operation) are set to stay as results after legalization but lhlo.TerminatorOp doesn't accept any operands. Therefore, BufferAssignmentReturnOpConverter must be replaced with a manual conversion that removes all operands of mlhlo.ReturnOp and inserts copy operations in their places.
