Do not register edges for statements not understood.
Previously, all gimple_cond types were undserstoof, with float values,
this is no longer true. We should gracefully do nothing if the
gcond type is not supported.
PR tree-optimization/106510
gcc/
* gimple-range-fold.cc (fur_source::register_outgoing_edges):
Check for unsupported statements early.
gcc/testsuite
* gcc.dg/pr106510.c: New.
