When creating a new closure, we check feedback vector for any optimized
code and install it on the newly created closure. We evict the optimized
code from the feedback vector if it is marked for deoptimization. We
used to evict the code before creating the new closure. However,
creating a new closure could cause allocation failures and hence trigger
a GC. This could mark optimized code on feedback vector for
deoptimization if any weak objects held by optimized code are GC'ed.
This cl delays the eviction unitl after the closure was created.
