Replace another snippet with a call to gimple_range_ssa_names.
When the original patch was applied, I missed a spot which could
also be rewritten to use gimple_range_ssa_names.
* tree-ssa-threadbackward.cc
(back_threader::find_paths_to_names): Replace sequence with
a call to gimple_range_ssa_names.
