Target ABI: improve call parameters extensions handling (#100757)
For the purpose of verifying proper arguments extensions per the target's ABI,
introduce the NoExt attribute that may be used by a target when neither sign-
or zeroextension is required (e.g. with a struct in register). The purpose of
doing so is to be able to verify that there is always one of these attributes
present and by this detecting cases where sign/zero extension is actually
missing.
As a first step, this patch has the verification step done for the SystemZ
backend only, but left off by default until all known issues have been
addressed.
Other targets/front-ends can now also add NoExt attribute where needed and do
this check in the backend.
