This reverts commit a2052b8794cb5abac131cd62f68505eebcfaffcb.
This commit renamed some Vulkan identifiers that shouldn't have been
renamed, e.g., `SPV_KHR_storage_buffer_storage_class`.
This commit moves MemRef memory space to SPIR-V storage class
conversion out of the main SPIR-V type converter. Now the mapping
should happen as a prelimiary step before performing the final
conversion to SPIR-V. Flows are expect to write their own memory
space mappings like the `MapMemRefStorageClassPass` to handle
memory space mappings according to their needs.
This is needed because SPIR-V is serving multiple client APIs,
including Vulkan and OpenCL. Different client APIs might want
to use different storage classes for buffers in a particular
memory space, e.g., `StorageBuffer` for Vulkan vs. `CrossWorkgroup`
for OpenCL when converting the default 0 memory space. Hardcoding
a specific mapping makes that hard. While it's possible to embed
selection logic further inside the main type converter, it will
make the main type converter even complicated. So it's better to
separate the concerns, as mapping the memory space is really
concretizing the meaning of those numeric memory spaces in the
particular context of SPIR-V lowering.

* It works similar to scf.for coversion, but convert condition and yield ops as part of scf.whille pattern so it don't need to maintain external state

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. For ops that
don't have a SPIR-V spec counterpart, we use spv.mlir.snake_case.

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 8aa6c3765b924d86f623d452777eb76b83bf2787.
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:

Previously all SCF to SPIR-V conversion patterns were tested as
the -convert-gpu-to-spirv pass. That obscured the structure we
want. This commit fixed it.
