Removed redundant ops from the standard dialect that were moved to the
`arith` or `math` dialects.
Renamed all instances of operations in the codebase and in tests.

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

This commit introduced a cyclic dependency:
Memref dialect depends on Standard because it used ConstantIndexOp.
Std depends on the MemRef dialect in its EDSC/Intrinsics.h
Working on a fix.
This reverts commit 8aa6c3765b.
Create the memref dialect and move several dialect-specific ops without
dependencies to other ops from std dialect to this dialect.
Moved ops:
AllocOp -> MemRef_AllocOp
AllocaOp -> MemRef_AllocaOp
DeallocOp -> MemRef_DeallocOp
MemRefCastOp -> MemRef_CastOp
GetGlobalMemRefOp -> MemRef_GetGlobalOp
GlobalMemRefOp -> MemRef_GlobalOp
PrefetchOp -> MemRef_PrefetchOp
ReshapeOp -> MemRef_ReshapeOp
StoreOp -> MemRef_StoreOp
TransposeOp -> MemRef_TransposeOp
ViewOp -> MemRef_ViewOp
The roadmap to split the memref dialect from std is discussed here:

This commit does the renaming mentioned in the title in order to bring

This PR adds support for identified and recursive structs.
This includes: parsing, printing, serializing, and
deserializing such structs.
The following C struct:
```C
struct A {
A* next;
};
```
which is translated to the following MLIR code as:
```mlir
!spv.struct<A, (!spv.ptr<!spv.struct<A>, Generic>)>
```
would be represented in the SPIR-V module as:
```spirv
OpName %A "A"
OpTypeForwardPointer %APtr Generic
%A = OpTypeStruct %APtr
%APtr = OpTypePointer Generic %A
```
In particular the following changes are included:
- SPIR-V structs can now be either identified or literal
(i.e. non-identified).
- All structs now have their members surrounded by a ()-pair.
- For recursive references,
(1) an OpTypeForwardPointer instruction is emitted before
the OpTypeStruct instruction defining the recursive struct
(2) an OpTypePointer instruction is emitted after the
OpTypeStruct instruction which actually defines the recursive
pointer to struct type.

This patch extends the AccessChainOp index type handling to be able to deal with
all Integer type indices (i.e., all bit-widths and signedness symantics).
There were two ways of achieving this:
1- Backward compatible: The new way of handling the indices will assume that
an index type is i32 by default if not specified in the assembly format,
this way all the old tests would pass correctly.
2- Enforce the format: This unifies the spv.AccessChain Op format and all the old
tests had to be updated to reflect this change or else they fail.
I picked option-2 to unify the Op format and avoid having optional index-type fields
that can lead to somewhat confusing tests format and multiple representations for
the same Op with undocumented assumption that an index is i32 unless stated.
Nonetheless, reverting to option-1 should be straightforward if preferred or needed.

Summary:
Use a nested symbol to identify the kernel to be invoked by a `LaunchFuncOp` in the GPU dialect.
This replaces the two attributes that were used to identify the kernel module and the kernel within seperately.

Summary:
Workgroup size is written into the kernel. So to properly modelling
vulkan launch, we have to skip local workgroup size for vulkan launch
call op.

This commit added stride support in runtime array types. It also
adjusted the assembly form for the stride from `[N]` to `stride=N`.
This makes the IR more readable, especially for the cases where
one mix array types and struct types.

This commits changes the definition of spv.module to use the #spv.vce
attribute for specifying (version, capabilities, extensions) triple
so that we can have better API and custom assembly form. Since now
we have proper modelling of the triple, (de)serialization is wired up
to use them.
With the new UpdateVCEPass, we don't need to manually specify the
required extensions and capabilities anymore when creating a spv.module.
One just need to call UpdateVCEPass before serialization to get the
needed version/extensions/capabilities.

* Updates LaunchFuncToVulkanCalls instrumentation pass, adds `initVulkan` and `deinitVulkan` runtime calls.
* Adds `bindResource` call to bind specifc resource by the given descriptor set and descriptor binding.
* Eliminates static construction and desctruction of `VulkanRuntimeManager`.
