tests: Cover all immediate numbers

[howjmay]

This PR use X-Macro skill to iterate all the possible immediate numbers for the intrinsics that allow immediate numbers only.

closes #582

@jserv Do you think this PR is a good idea? I think even though this PR covers all the possible immediate numbers, the implementation become less readable and harder to implement.
However, in the meantime, I don't think the tests will be ones that changed frequently, or even won't be changed at all in the future.

Alternatively, we can even generate test cases via shell scripts with more flexibility.

May I ask for more details?

Check this: https://github.com/IBM/microprobe/tree/master/targets/riscv/examples
There are various template-based generators.

I didn't see the templates for SSE. I saw only PowerPC and RISCV only. Not sure how can we generate tests by this. I may need more research

[howjmay]

So the current change is an acceptable one or I should discard it?

[howjmay]

I will extend the same implementation to the other instrinsics with immediate numbers
