Rahul Joshi 0800423d27 [LMHLO] Simplify FusionOp::getInputBuffers() and friends. 
- No need to walk the entire region, instead just iterate over the top level operations in
  the region attached to the fusion op.

Geoffrey Martin-Noble 38d0f96709 Switch deps AllPassesAndDialectsNoRegistration -> AllPassesAndDialects 
These targets are now identical as all registration is explicit.
Temporarily leaving the old target as a (deprecated) alias while
changes propagate.

Adrian Kuegel c8157ba4df Move code from helper struct to the only user. 
We don't need the separate helper struct anymore, because it is now only used
in one place.

Adrian Kuegel 4033a56750 Add special cases for SelectOp rank specialization. 
We now use the same special cases for all ops with arity >= 2.
For binary ops, we now have only one special case if at least one of the
operands has exactly one element. In that case, we reshape both operands to
rank 1. Before, we had separate special cases whether the left-hand side
or the right-hand side have a scalar shape.

A. Unique TensorFlower 9206805c58 [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.

A. Unique TensorFlower 8ade5d78c8 [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.

Adrian Kuegel c1a6ae8994 Generalize the HloBinaryElementwiseAdaptor 
We can use it also for ternary ops like Select if we change the signature so
that a ValueRange is passed in.
Also remove special casing for HloComplexAdaptor. It can be handled with the
generic adaptor as well.
