Are there also some other optimisation passes working on the GIMPLE/SSA
representation which make use of any machine-dependent features?

Yes. Passes like vectorization and loop optimizations will use so called 'target hooks' which allow the high-level passes to query the target for various capabilities and attributes. See the tree-vect*.c files for several examples.
