Differentiate between IR_KPTR and IR_KKPTR.

Browse Source 
IR_KPTR holds a const pointer to possibly non-const content.
IR_KKPTR holds a const pointer to definitely const content.
Note that only content known by the VM to be const qualifies.
Content tagged as const by users (e.g. const char *) doesn't.
