It is common to have ABI requirements for illegal types: For example, two i64 argument parts that originally came from an fp128 argument may have a different call ABI than ones that came from a i128 argument. The current calling convention lowering does not provide access to this information, so backends come up with various hacks to support it (like additional pre-analysis cached in CCState, or bypassing the default logic entirely). This PR adds the original IR type to InputArg/OutputArg and passes it down to CCAssignFn. It is not actually used anywhere yet, this just does the mechanical changes to thread through the new argument.
