tree-optimization/109524 - ICE with VRP edge removal
VRP queues edges to process late for updating global ranges for
__builtin_unreachable. But this interferes with edge removal
from substitute_and_fold. The following deals with this by
looking up the edge with source/dest block indices which do not
become stale.
PR tree-optimization/109524
* tree-vrp.cc (remove_unreachable::m_list): Change to a
vector of pairs of block indices.
(remove_unreachable::maybe_register_block): Adjust.
(remove_unreachable::remove_and_update_globals): Likewise.
Deal with removed blocks.
* g++.dg/pr109524.C: New testcase.
