39181: Add PM_SINGLE and use for compstate.
This flags that compstate (or any other special) can only have a single instance and an attempt to create a new one is an error. Given the very fiddly semantics of compstate any other usage seems pointless. No investigation yet of other variables that could use this. Note it's still possible to hide such variables; only instances that keep the special nature are affected.
