Abstract interesting ssa-names from GORI.
Provide a routine to pick out the ssa-names from interesting statements.
* gimple-range-fold.cc (gimple_range_ssa_names): New.
* gimple-range-fold.h (gimple_range_ssa_names): New prototype.
* gimple-range-gori.cc (range_def_chain::get_def_chain): Move
code to new routine.
