Joe Groff e3fef32a9b SILGen: Don't use diagnoseUnexpectedEnumCase intrinsic for noncopyable enums. ...

It should be impossible to reach an unexpected case statically while using
noncopyable enums, and the intrinsic has not been updated to remove its
`Copyable` requirement. Emit a plain trap in cases where this code emission
path might still occur, such as when a redundant but incomplete set of case
patterns follow a wildcard pattern. Fixes rdar://130037881.
