Thinking about this further I realized that in order to inline the call we would need to have CallLinkInfo for the getter Callee. That would tell us what address to call when the function we are calling gets tiered up. Unfortunately, as far as I know, we don't have any kind of CallLinkInfo for the LLInt. Without, CallLinkInfo I think you would need to call into C++ to find the call location anyway. Let me look into this further but I think it might not be worthwhile to inline normal getters. We should still be able to  inline custom getters however.
