  TableGen: Deterministically order predicate groups by calling convention

The predicate-group sort in emitSystemRuntimeLibrarySetCalls keyed only on the
predicate name, so two groups sharing a predicate name but differing in calling
convention (e.g. isOSWindows with the default CC vs ARM_AAPCS) tied and could
emit in an unstable order. Break the tie on the calling convention name so the
generated output is deterministic.
