The actual instruments used by xtabond2 are temporary variables. The
list of these temporary variables is stored in the local macro zvars.

Look for the following code in xtabond2.ado:

	_rmcoll `*' `ivinsts' `cons1', noconstant
	local zvars `r(varlist)'

This is gives you the list of the temporary variables that form the
instruments matrix after dealing with collinearity.
