Nice script!
The clean up commands may be simplified using this scheme

```
#!/bin/bash
OUTDIR=$(dirname $(realpath -s $0))

dir=$(mktemp -d)
trap "rm -r $dir" EXIT
cd $dir
cat > lib.h <<EOF
...
EOF
...
rm -f $OUTDIR/thinlto_indirect_call_promotion.profraw
LLVM_PROFILE_FILE=$OUTDIR/thinlto_indirect_call_promotion ./a.out
```
