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

spv.Ordered/spv.Unordered are meant for OpenCL Kernel capability.
For Vulkan Shader capability, we should use spv.IsNan to check
whether a number is NaN.
Add a new pattern for converting `std.cmpf ord|uno` to spv.IsNan
and bumped the pattern converting to spv.Ordered/spv.Unordered
to a higher benefit. The SPIR-V target environment will properly
select between these two patterns.

Define OrderedOp and UnorderedOp instructions in SPIR-V and convert
cmpf operations with `ord` and `uno` tag to these instructions
respectively.

In the overwhelmingly common case, enum attribute case strings represent valid identifiers in MLIR syntax. This revision updates the format generator to format as a keyword in these cases, removing the need to wrap values in a string. The parser still retains the ability to parse the string form, but the printer will use the keyword form when applicable.

This commit moves dangling ops in the main ops.td file to the proper
file matching their categories. This makes ops.td as purely including
all category files.

This commit adds support for (de-)serializing SpecConstantOpeation. One
thing worth noting is that during deserialization, we assign a fake ID to
enclosed ops inside SpecConstantOpeation. We need to do this in order
for deserialization logic to properly update ID to value map and to
later reference the created value from the sibling 'spv::YieldOp'.

This commit shuffles SPIR-V code around to better follow MLIR
convention. Specifically,
* Created IR/, Transforms/, Linking/, and Utils/ subdirectories and
moved suitable code inside.
* Created SPIRVEnums.{h|cpp} for SPIR-V C/C++ enums generated from
SPIR-V spec. Previously they are cluttered inside SPIRVTypes.{h|cpp}.
* Fixed include guards in various header files (both .h and .td).
* Moved serialization tests under test/Target/SPIRV.
* Renamed TableGen backend -gen-spirv-op-utils into -gen-spirv-attr-utils
as it is only generating utility functions for attributes.
