Comment(by rtoy):

 This should be fixed in the 2008-12 snapshot.

 We now delay {{{logand-defopt-helper}}}until after {{{IR2}}} optimizations
 are done so that we give the compiler a chance to derive all of the
 variable types.  Then we run this optimizer.  This will cause some
 increase in compilation time for code that deals with modular arithmetic,
 but we should get better behaved modular arithmetic.
