so that Eva won't raise an alarm on them.

Avoid warning about missing proto during typechecking.
Also changes a warning into an error, and improves the error message.

According to the kernel option -warn-invalid-pointer.

In order to avoid an undefined behavior in the C code generated for this macro
(conversion from an absolute integer to a pointer).

When -absolute-valid-range is enabled, the Null base has a Known validity,
but a pointer can always points to Null+{0}.

Complies with the kernel option -warn-invalid-pointers.

[Instantiate] Fix different failures

See merge request frama-c/frama-c!2592

Run 0 tests the default configuration of Frama-C: no downcast alarms, except
for pointers.
Runs 1 to 3 correspond to the previous run with successive -then, and test:
- emission of signed downcast alarms (option -warn-signed-downcast)
- emission of unsigned downcast alarms (option -warn-unsigned-downcast)
- the relaxed semantics of the Eva option -eva-warn-signed-converted-downcast
Run 4 disables all downcast alarms, including downcast of pointer values.
