* An instance of struct TriggerStack stores information required during code

* "pTriggerStack" member of the Parse structure.
*
* The pTab member points to the table that triggers are being coded on. The
* newIdx member contains the index of the vdbe cursor that points at the temp
* table that stores the new.* references. If new.* references are not valid
* for the trigger being coded (for example an ON DELETE trigger), then newIdx
* is set to -1. The oldIdx member is analogous to newIdx, for old.* references.
*
* The ON CONFLICT policy to be used for the trigger program steps is stored
* as the orconf member. If this is OE_Default, then the ON CONFLICT clause
* specified for individual triggers steps is used.
*
* struct TriggerStack has a "pNext" member, to allow linked lists to be
* constructed. When coding nested triggers (triggers fired by other triggers)
* each nested trigger stores its parent trigger's TriggerStack as the "pNext"
* pointer. Once the nested trigger has been coded, the pNext value is restored
* to the pTriggerStack member of the Parse stucture and coding of the parent
* trigger continues.
*
* Before a nested trigger is coded, the linked list pointed to by the
* pTriggerStack is scanned to ensure that the trigger is not about to be coded
* recursively. If this condition is detected, the nested trigger is not coded.
