MaheshRavishankar 615167c9f7 [mlir]][SPIRV] Define OrderedOp and UnorderedOp and add lowerings from Standard.
Define OrderedOp and UnorderedOp instructions in SPIR-V and convert
cmpf operations with `ord` and `uno` tag to these instructions
respectively.

Lei Zhang a5d5d29125 Update SPIR-V.md
This CL updates SPIR-V.md to reflect recent developments
in the SPIR-V dialect and its conversions.

Along the way, also updates the doc for define_inst.sh.

Mahesh Ravishankar 80ec474a65 Add atomic operations to SPIR-V dialect.
Some changes to the dialect generation script to allow specification
of different base class to derive from in ODS.

Denis Khalikov d423d4a338 [spirv] Add cast operations
This CL added op definitions for a few cast operations:

* OpConvertFToU
* OpConvertFToS
* OpConvertSToF
* OpConvertUToF
* OpUConvert
* OpSConvert
* OpFConvert

Also moved the definition of spv.Bitcast to the new file.

Closes tensorflow/mlir#208 and tensorflow/mlir#174

Mahesh Ravishankar 2f7bb1e25f Add support for Logical Ops in SPIR-V dialect
Add operations corresponding to OpLogicalAnd, OpLogicalNot,
OpLogicalEqual, OpLogicalNotEqual and OpLogicalOr instructions in
SPIR-V dialect. This needs changes to class hierarchy in SPIR-V
TableGen files to split SPIRVLogicalOp into SPIRVLogicalUnaryOp and
SPIRVLogicalBinaryOp. All derived classes of SPIRVLogicalOp are
updated accordingly.

Update the spirv dialect generation script to
1) Allow specifying base class to use for instruction spec generation
and file name to generate the specification in separately.
2) Use the existing descriptions for operations.
3) Update define_inst.sh to also invoke define_opcode.sh to also
define the corresponding SPIR-V instruction opcode enum.

Mahesh Ravishankar 49c3e4a508 Add floating-point comparison operations to SPIR-V dialect.
Use the existing SPV_LogicalOp specification to add the floating-point
comparison operations (both ordered and unordered versions).
To make it easier to import the op-definitions automatically modify
the dialect generation script to update the different .td files based
on whether the operation is an arithmetic op, logical op, etc. Also
allow specification of multiple opcodes with define_inst.sh.
Since this reuses the SPV_LogicalOp framework, no tests specific to
the floating point comparison ops are added with this CL.

Lei Zhang bd484f17a0 [spirv] Add script to auto-generate SPIR-V op template from spec
SPIR-V has a JSON grammar file that defines the syntax of SPIR-V
instructions. However, its lacks fine-grained constraints on
instruction operands; those information is only available as
natural language sentences in the SPIR-V spec, which also contains
the detailed documentation for each SPIR-V instruction.

This CL pulls information from both the JSON grammar and HTML
spec. It right now uses the former to deduce the arguments and
results (with coarse-grained constraints) and the latter for
documentation. In the future we can add the functionality to
match certain natural language sentences for more fine-grained
constraints, but right now the developer is expected to update
the generated op definition. This should serve as a nice
bootstrap step to save efforts.
