* ChangeLog: Add following to my previous description:
(if_convertible_loop_p): Clear aux field of incoming edges if bb
contains phi node.
From-SVN: r126214
"basic_block" description as its third argument. Update function
calls to get destination bb from "edge" argument. Save "cond" into
aux field of the edge. Update prototype for changed arguments.
+ (if_convertible_loop_p): Clear aux field of incoming edges if bb
+ contains phi node.
(find_phi_replacement_condition): Operate on incoming edges, not
on predecessor blocks. If there is a condition saved in the
incoming edge aux field, AND it with incoming bb predicate.
