will STM can help implement concurrent garbage collector?

No, that's the wrong way around. A concurrent GC might be needed at some point in order to help STM. But you don't want to write a GC *using* the STM features. Instead we need to write a GC taking STM into account, and probably sharing the same read/write barriers; if anything, it makes the job harder than "just" writing STM or "just" writing a concurrent GC.
