The documentation still referred to typed instructions having a
Parse::Node field, however that was removed and moved to the InstStore
in f197219c10.
Then GetParseNode() was renamed to GetNodeId() in 86a7c9ff45 and
then GetLocationId() in b079acd86f and finally GetLocId() in
b5d28f2c4b.
The comment in typed_inst.h mentions only three fields now, but some
types still have four, thanks to the unmentioned `ElementIndex index`
field. Normally this field comes last, after the `[...]Id` fields except
for in one case, AssociatedEntity. Rather than write ambiguously ordered
documentation, update the comment to and docs to say that the
ElementIndex comes last, and move it to the last position in
AssociatedEntity. Tests are rebased accordingly.
