Currently, the LRB slow-path call does 2-3 calls in a row:
compiled code -> runtime entry
runtime entry -> ShBS::load_reference_barrier_mutator()
ShBS::lrb_mutator() -> ShBS::lrb_mutator_work()
The first in unavoidable, but none of the other two are marked inlined and are in a separate compilation-unit. Further, the middle-call is not needed. We can call straight from ShRuntime into the templated-inlined lrb_mutator() method.
