Because caller stores callee to a specific stack slot, we do not need to generate LLInt/IPInt entrypoint thunk anymore.
This patch wipes it. And we move LLIntCallee / IPIntCallee generation from the last part of LLIntPlan / IPIntPlan to each function compilation.
We also move entrypoint thunk generation from the last phase to the each function compilation.
