This CL adds the basic SPIR-V serializer and deserializer for converting
SPIR-V module into the binary format and back. Right now only an empty
module with addressing model and memory model is supported; (de)serialize
other components will be added gradually with subsequent CLs.
The purpose of this library is to enable importing SPIR-V binary modules
to run transformations on them and exporting SPIR-V modules to be consumed
by execution environments. The focus is transformations, which inevitably
means changes to the binary module; so it is not designed to be a general
tool for investigating the SPIR-V binary module and does not guarantee
roundtrip equivalence (at least for now).

https://www.khronos.org/registry/spir-v/specs/1.0/SPIRV.html#OpTypeImage.
Add new enums to describe Image dimensionality, Image Depth, Arrayed
information, Sampling, Sampler User information, and Image format.
Doesn's support the Optional Access qualifier at this stage
Fix Enum generator for tblgen to add "_" at the beginning if the enum
starts with a number.

This name has caused some confusion because it suggests that it's running op verification (and that this verification isn't getting run by default).

This is a direct modelling of SPIR-V's OpVariable. The custom assembly format
parsers/prints descriptor in a nicer way if presents. There are other common
decorations that can appear on variables like builtin, which can be supported
later.
This CL additionally deduplicates the parser/printer/verifier declaration
in op definitions by adding defaults to SPV_Op base.

Pointer types need to specify the storage class. We use the utility functions
generated from SPV_StorageClassAttr to parse and print the storage classes.
Also improved the case that no element type is provided for (runtime) array.

This CL adds SPV_ModuleEndOp for terminating the only block inside a
SPV_ModuleOp's only region. Verification now enforces a spv.module only
contains func or spv.* ops and no external or nested functions are
present. Because of the structural requirement of a block, spv.Return
is also added in this CL.
PiperOrigin-RevId: 251510706
This op defines a SPIR-V module using a MLIR region. The region contains
one block. Module-level operations, including functions definitions,
are all placed in this block.
This CL extracts common definitions from SPIRVOps.td into SPIRVBase.td.
The new op is placed in SPIRVStructureOps.td.

This CL sets up the basic structure for a SPIR-V dialect: operation
definition specification, dialect registration, testing, etc.
A single op, FMul, is defined and tested to showcase.
The SPIR-V dialect aims to be a simple proxy for the SPIR-V binary format
to enable straightforward and lightweight conversion from/to the binary
format. Ops in this dialect should stay as the same semantic level and
try to be a mechanical mapping to the corresponding SPIR-V instructions;
but they can deviate representationally to allow using MLIR mechanisms.
