Adrian Kuegel fa059259bc Add template for tf.Cast 
Also generate the kernels for all types of casts between signed int and float types.
This requires some adaptations to our build macros so that we can also specify the
output type of a kernel.

Rahul Joshi 44deae2aa1 [MLIR:HLO] Extend AllReduce to support multiple inputs and results (to model tuples). 
- Instead of SameTypeOperands, add custom verification to check if operands and
  results pairwise have the same type.

Allow for relative tolerance in unary kernel tests. In case of the cosh kernels,
this allows to accept an observed difference of 5.6e-8 between the kernel and
the `std::cosh` reference (32829984.568665262 vs. 32829984.568665318) in one of
the test cases.

Hanhan Wang 8f58f844e5 Upstream mhlo.dot lowering to Linalg to MHLO repo. 
We prototyped the lowering from mhlo.dot to linalg.matmul in IREE. Since Linalg
now supports matmul in tensors world, we can move the lowering logic to tensors
world, and upstream to legalize_to_linalg.cc. The patch lowers the mhlo.dot to
the linalg.matmul/matvec/dot in tensors world.

Stephan Herhut ccdd07f8e4 Prepare to remove tensor_load and tensor_store special handling from hlo to lhlo legalization. 
This updates the tests to no longer rely on tensor_store. Once all users of this behavior have adopted, the tensor_store support will be removed.

Tres Popp a42213b870 Define lowering of [l]mhlo.pow. 
For floating point operations, this uses std.pow.
For integer operations, this lowers to a loop.
This adds a dependency on scf.

Smit Hinsu 9466cffaf3 Restrict CHLO Acos and Sinh op lowering to non complex types 
These are failing for complex types. Complex types require special handling. We have a fallback lowering for these ops so we can disable complex element types for now.

Smit Hinsu 8d051723c0 Use InferTypeOpInterface for HLO AbsOp and fix result shape inference 
Shape inference in case of ops with complex element types need to use the element type of complex as the result element type and not the full operand type.

Before:
"mhlo.abs"(%arg0) : (tensor<4xcomplex<f32>>) -> tensor<4xtensor<4xcomplex<f32>>>
After:
"mhlo.abs"(%arg0) : (tensor<4xcomplex<f32>>) -> tensor<4xf32>

Adrian Kuegel 61244b136c Try to avoid a segfault if we don't support a lowering. 
It can happen that a lowering for a certain type is not implemented yet.
We should not segfault in such a case, but instead return a failure().
