  Fix -Wtype-limits warning on mips

Reviewed by Mark Lam.

When setupStubCrossArgs is instantiated with NumCrossSources == 0, we
get
    warning: comparison of unsigned expression in ‘< 0’ is always false [-Wtype-limits]

Don't enter the loop if NumCrossSources is 0. We still need to mark the
parameters unused in the NumCrossSources == 0 path, to avoid
-Wunused-but-set-parameter warnings.
