To be able to target standard processors, reverse if-conversion can be
used to create if-statements and branches based on the predicated
instructions. Scheduling over multiple blocks can then be performed by
adding predicates, doing if-conversion ([\#1c8]) and hyperblock
scheduling ([\#1b8]). Then, to convert back to a basic-block view of the
code, reverse if-conversion can be used. This therefore has a similar
effect to scheduling instructions using trace scheduling ([\#3c3f]).
