Fix vm/cc/StaticNonNullSumCallCodegen.

Fix vm/cc/StaticNonNullSumCallCodegen.

Instead of passing null wrapped in the Smi handle use Instance handle.

We have the following behavior:

Smi::ZoneHandle().IsSmi() -> true
Smi::Cast(Smi::ZoneHandle()).Value() -> assertion failure

This kind of behavior is completely unexpected in most parts of the system.

TBR to make the bot green

However we might want to fix the handle system.

File runtime/vm/code_generator_test.cc (right):

runtime/vm/code_generator_test.cc:512: arguments->Add(new LiteralNode(kPos,
Instance::ZoneHandle()));
Object::null_object() would be the correct thing to use here.
