That is interesting. IMHO we should change GIMPLE_COND to have only a
boolean variable. My only argument for that is that it would make the
IL more simple, since there would be only one place to look for
comparisons (on GIMPLE_ASSIGN).

This problems looks like a more convincing argument. What do you think about it?

We changed GIMPLE to always use canonical comparisons because they are more convenient than SSA_NAMEs. A single SSA_NAME is actually less convenient than a comparison in most cases.
