Adds the necessary bits to lower arguments and return values of type unsigned int for the x86_64 target. This includes adding logic for extend and direct argument-passing types.

How does this fits with the plan we discussed about incremental support already as part of the oficial pipeline? Can you please outline the plan?
I backtracked to the original plan: implement the basics CC lowering bits first, then flip the -fclangir-call-conv-lowering flag.
Moving this pass into the official pipeline in its current state requires too many logical changes just for the code to work, changes that would later have to be reverted.
