This is the result of an audit of all of the ABIs in clang to implement and enable the type for those targets. Additionally, this finds an issue with integer-promotion passing for a few platforms when using _ExtInt of < int, so this also corrects that resulting in signext/zeroext being on a params of those types in some platforms.
