Converts the macros to function calls to an actual probe. Some probes are excluded to avoid recursing into dtrace.
Sample use:
```
dtrace -n 'sdt:profile:predict: { @[stringof(args[2]), arg3, arg0 == arg1] = count(); }' -o out
```
```
cat out | awk 'NF { all[$1 ":" $2] += $4; if ($3) { hit[$1 ":" $2] = $4; if (miss[$1 ":" $2] == 0) miss[$1 ":" $2] = 0; } else { miss[$1 ":" $2] = $4; if (hit[$1 ":" $2] == 0) hit[$1 ":" $2] = $4; } } END { for (l in all) print l " " all[l] " " hit[l] " " miss[l] " " hit[l] * 100 / (all[l]) }' | sort -rnk 5 | less
```
