vnf,runrom: detect bad data access

This includes detection for:

- Stack underflows (it was theoretically already there but it had never
  been properly tested).
- Load/store out of bounds for a given variable known via the .nasm/
  directory.
- Load out of bounds on a set of data referenced via a raw label (see
  commit aa5174fc055d ("xixanta: Add an hint for the ending of data
  labels")).
