Basically, just run queens.c with PGO (IR instrumentation).

CLANG_PATH="/home/davide/work/llvm/build-release/bin/clang"
PROFDATA_PATH="/home/davide/work/llvm/build-release/bin/llvm-profdata"
OPT_VIEWER_PATH="/home/davide/work/llvm/tools/opt-viewer/opt-viewer.py"
OPT_LEVEL="-O3"
TEST_NAME="queens"

rm -f ${TEST_NAME} ${TEST_NAME}.pgo o3.yaml pgo.yaml default.profraw
default.profdata
rm -rf pgotrace
mkdir pgotrace

# PGO + -O3
${CLANG_PATH} -fprofile-generate=pgotrace -fexperimental-new-pass-manager
${OPT_LEVEL} ${TEST_NAME}.c -o ${TEST_NAME}
env LLVM_PROFILE_FILE=pgotrace/default.profraw ./${TEST_NAME}
${PROFDATA_PATH} merge pgotrace/default.profraw -o default.profdata

Crashes with: (during -fprofile-use)
