ORCA-C/Tests/Conformance/C17.8.0.1.CC
Stephen Heumann 52f512370f Update tests to account for recent ORCALib changes.
These involve recent standards-conformance patches for printf and scanf, which changed some (non-standard) behaviors that the test cases were expecting.

I also fixed a couple things that clang flagged as undefined behavior, even though they weren't really causing problems under ORCA/C.
