[MLIR] Fix merge of assuming ops
...
Assuming ops can only be merged if their witnesses will dominate the merged
assuming op. This is not the case if the second op's witness is a result of the
first.

[MLIR][MHLO] Do not yield results of ops that were moved out of assuming regions
...
When an op is moved out of an assuming region we already know statically that it
is independent of the assuming region. Hence, there is no need to yield its
results.

[MLIR][MHLO] Move `cstr_broadcastable` and `shape_of` out of `assuming` regions
...
Add pattern to move operations out of assuming op. This only valid for
constraint-independent ops, like `cstr_broadcastable` and `shape_of`. It will
eventually allow to make assuming regions' constraints independent from each
other so that they can be merged.
