Updates LLVM usage to match

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.

A. Unique TensorFlower e87d53742b 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.

Rahul Joshi dbbdfea95b [MLIR:HLO] Generate enum decls for HLO and LHLO GPU dialects. 
- Split out enum definitions in hlo dialect into a separate .td file (similar to structs)
  and generate enum decl/defs for these enums.
- Also split out the LHLO GPU enums into a separate .td file and generate enum
  decl/defs for these enums as well.
- Remove unused dialect from ConvolutionAttributes and generate lhlo_gpu enums.
- Add appropriate namespace for all the enums.

- Map Custom call for GEMM in XLA HLO to Gemm/Gemm bias operations in LHLO GPU
  dialect.
- Make 'algorithm' an optional attribute to better match with XLA HLO backend config.
- Replace 'alpha' with 'alpha_real' and 'alpha_complex' to support complex GEMM correctly.
- Generate GemmThunk off of LHLO GPU Gemm operations.
