enable_unary_reductions(graph) in -Jred cause runtime errors of 18 llvm-test-suite tests

Recreate
Modify jlm/llvm/opt/reduction.cpp (line 134)

static void
reduce(RvsdgModule & rm, util::StatisticsCollector & statisticsCollector)
{

and disable all optimizations except the load_reduction, i.e.,
// enable_mux_reductions(graph);
// enable_store_reductions(graph);
// enable_load_reductions(graph);
// enable_gamma_reductions(graph);
enable_unary_reductions(graph);
// enable_binary_reductions(graph);

Compile the file separately to avoid having to comment out unused functions:
/usr/lib/llvm-16/bin/clang++ -c --std=c++17 -gdwarf-4 -g -DJLM_DEBUG -DJLM_ENABLE_ASSERTS -I. -I/usr/lib/llvm-16/include -I. -I/usr/lib/llvm-16/include -o build/jlm/llvm/opt/reduction.la jlm/llvm/opt/reduction.cpp

Then compile jlm with debug:
make jlm-debug -j nproc

Then run the llvm-test-suite
make llvm-run-red
