Currently there is no way to add in development features to the ML
regalloc evict advisor which is useful to have when working on feature
engineering/improving the current model. This patch adds in the ability
to add in development features to the ML regalloc evict advisor which
are gated by a runtime flag and not added in at all if not compiled in
LLVM development mode. This sets the stage for future work where we are
planning on upstreaming some of the newer features that we are currently
experimenting with.
