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.

- Extend spirv::ConstantOp::getZero/One to handle float, vector of int, and vector of float.
- Refactor ZeroExtendI1Pattern to use getZero/One methods.
- Add one more test for lowering std.zexti which extends vector<4xi1> to vector<4xi64>.

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

The dialect conversion framework was enhanced to handle type
conversion automatically. OpConversionPattern already contains
a pointer to the TypeConverter. There is no need to duplicate it
in a separate subclass. This removes the only reason for a
SPIRVOpLowering subclass. It adapts to use core infrastructure
and simplifies the code.
Also added a utility function to OpConversionPattern for getting
TypeConverter as a certain subclass.

This commit adds a new trait that can be attached to ops that have
unsigned semantics.
TODO:
- Check if other places in code can use the new attribute (possibly in this patch).
- Add a similar `SignedOp` attribute (in a new patch).

This commit renames various SPIR-V related conversion files for
consistency. It drops the "Convert" prefix to various files and
fixes various comment headers.
