DMC++ has similar switches, but nobody uses them, and they are pretty much 
useless anyway, because:

1. you need to be a compiler guy to know what they mean - very few people know 
what "code hoisting" is

2. it's the combination of optimizations that produces results - they are not 
independent of each other

This is why I didn't include such switches in DMD.
