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().

A. Unique TensorFlower f0c2695d31 Fix SignOp lowering for floating point values. 
It didn't return 0 for 0.0 and -0.0.
Currently we emit -0.0 for -0.0 which is correct according to the HLO dialect.
For the TF_SignOp we should emit 0.0 in that case, we will leave that as a TODO.
Enable the tests which work now, and add another one for Int64.
Also improve the registration code, we should not register the Int32 kernel.

Rahul Joshi f232da1f9d [MLIR:HLO] Add window_reversal attribute to convolution attributes. 
- Add this attribute to match the corresponding XLA HLO attribute on convolution
  operations.
- A true value indicates a reversal of the corresponding kernel spatial dimension.
- Since XLA builder does not support this attribute, use a custom HLO converted to map
  from mlir::mhlo::ConvOp to XLA.

Smit Hinsu bc7b6374c8 Fix handling of negative seeds in random number generator op kernels for XLA 
Casting negative s32 number to u64 directly will have leading 1s in the representation which is not what we want to get a single u64 out of two s32 seeds. Fixed this by first getting unsigned number of the same bit-width.

Phoenix Meadowlark c33bdcbd03 Remove fold of `mhlo.compare(%arg0, %arg0)` for floating types. 
Two tensors having the same SSA-value isn't sufficient for equality for floating types, as `NaN != NaN`. As written this causes `tf.IsNan` to [miscompile](https://github.com/google/iree/issues/4061).

Rahul Joshi e48881af81 [MLIR:LHLO_GPU] Add fused convolution operation without any side inputs. 
- Add a variant of the fused convolution that does not need a side input and side input scale.
- Rename the existing one to `ConvForwardFusedSideInputOp`.
- Update tests to exercise all variants of the convolution ops in the GPU dialect.
- Eliminate unused `LHLO_ExtentBuffer` and changed LHLO_Buffer to allow any integer element
  type to match what XLA can generate sometimes for scratch buffers.
