Note that pass_pre destroys PROP_no_crit_edges
2014-01-09 Tom de Vries <tom@codesourcery.com>
* tree-ssa-pre.c (pass_data_pre): Add comment about PROP_no_crit_edges
in properties_required. Add PROP_no_crit_edges to properties_destroyed.
* tree-ssa-sink.c (pass_data_sink_code): Remove PROP_no_crit_edges
from properties_required.
