This extension has been superseded by SPV_KHR_cooperative_matrix which
is supported across major vendors GPU like Nvidia, AMD, and Intel.
Given that the KHR version has been supported for nearly half a year,
drop the NV-specific extension to reduce the maintenance burden and code
duplication.
This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.
Extend SPIR-V target serialization and deserialization to handle coop
matrix types. Add a roundtrip test. In addition to `FileCheck` checks,
the resulting spirv binary also passes `spir-val` (external tool).
Also fix a type attribute bug surfaced by the `CooperativeMatrixLength`
op.
Multiple matrix operand attributes will be handled in a future patch to
reduce the scope.
Previously we are using IntegerAttr to back all SPIR-V enum
attributes. Therefore we all such attributes are showed like
IntegerAttr in IRs, which is barely readable and breaks
roundtripability of the IR. This commit changes to use
`EnumAttr` as the base directly so that we can have separate
attribute definitions and better IR printing.

SPIR-V specification does not require a function to have a name
if it is an entry point. Adjust deserializer to allow those kinds
of SPIR-V binaries.

This provides a way to create an operation without manipulating
OperationState directly. This is useful for creating unregistered ops.

`(void)` was added when LogicalResult was marked as non

In SPIR-V, symbol names are encoded as `OpName` instructions.
They are not semantic impacting and can be omitted, which can
reduce the binary size.

The StringAttr version doesn't need a context, so we can just use the
existing `SymbolRefAttr::get` form. The StringRef version isn't preferred
so we want to encourage people to use StringAttr.
There is an additional form of getSymbolRefAttr that takes a (SymbolTrait
implementing) operation. This should also be moved, but I'll do that as
a separate patch.

Add a feature to `EnumAttr` definition to generate
specialized Attribute class for the particular enumeration.
This class will inherit `StringAttr` or `IntegerAttr` and
will override `classof` and `getValue` methods.
With this class the enumeration predicate can be checked with simple
RTTI calls (`isa`, `dyn_cast`) and it will return the typed enumeration
directly instead of raw string/integer.

To unify the naming scheme across all ops in the SPIR-V dialect, we are
moving from `spv.camelCase` to `spv.CamelCase` everywhere.

This makes ignoring a result explicit by the user, and helps to prevent accidental errors with dropped results. Marking LogicalResult as no discard was always the intention from the beginning, but got lost along the way.

Support OpImageType in SPIRV Dialect.
This change doesn't support operand AccessQualifier since
it is optinal and only enables under Kernel capability.

The SPIR-V spec uses OpSpecConstantOp. Using an inconsistent name
makes the dialect generation scripts fail. Update to use the right
