st: ivreg2 update

[Kit Baum <baum@bc.edu>]

The ivreg2 package of Baum, Schaffer and Stillman has been updated on  
the SSC Archive. Sune Karlsson has assisted us in identifying several  
changes that allow the -ivreg2- routine to run faster, particularly  
important in the context of a very large dataset with hundreds of  
regressors/instruments.

For the latest discussion of -ivreg2- features (and a comparison with  
Stata 10 -ivregress-), please see
