It's probably safer to have the real MDO.  The adapter is a real method, and it can (I think) reappear in the course of deoptimization and maybe even recompilation.

(This raises the question of whether we should be throwing away the adapters generated during compilation.  It seems non-parsimonious to do so, but it is simplest.)
