Kai added a comment.

Completely reworked the change.

- Rebased on latest main which has partial implementation of G_ZEXT (Currently, G_ZEXT and G_SEXT are only implemented for extending 32 -> 64 bit.)
- Removed support for G_CONSTANT. I will have a more complete solution ready in a follow up change.
- Added a mir test case to check the generated code
