Huh, forgot to fill in host and target...
This test used to be xfailed, btw, but should now pass due to generic
fabs optimizations.

Caused by:
2005-02-21  Kazu Hirata  <kazu@cs.umass.edu>

        * tree-cfg.c (fold_cond_expr_cond): New.
        (make_edges): Call fold_cond_expr_cond.
        (find_taken_edge): Accept nothing but INTEGER_CST.
        (find_taken_edge_cond_expr): Reject INTEGER_CST other than 0
        and 1.
        (find_taken_edge_switch_expr): Remove a check for INTEGER_CST.

Basically we are no longer folding it (because forward-progate does not call fold) and this was the only 
place where we called fold.
