This fixes a corner case where the {FastCloneShallowArrayStub} was used
for literals that are backed by a double backing store and would exceed
limits for new-space allocations on 32-bit architectures. The stub in
question does not support such literals, callers must use the runtime.
Note that this fix is for Ignition as well as FullCodeGenerator.
