The RegisterInput (NewTarget) was not correctly visited by the GC.
This:
- Creates a sentinel safepoint to indicate that the stack is not
fully created (we are in the stack guard call).
- Generalises RegisterInputs (we assumed only NewTarget before) and
save them in the graph.
- Pass the register input count via tagged_register_indexes in
this case.
