After this CL all liveedit tests call the same LiveEdit::PatchScript method. This method will be updated later. As well some new liveedit cctests added, unfortunately part of them do not work with current implementation.

This CL removes the weak-list of JS functions from the context and all the code that iterares over it. This list was being used mainly during deoptimization (for code unlinking) and during garbage collection. Removing it will improve performance of programs that create many closures and trigger many scavenge GC cycles. No extra work is required during garbage collection. However, given that we no longer unlink code from JS functions during deoptimization, we leave it as it is, and on its next activation we check whether the mark_for_deoptimization bit of that code is set, and if it is, than we unlink it and jump to lazy compiled code. This check happens in the prologue of every code object. We needed to change/remove the cctests that used to check something on this list. Working in x64, ia32, arm64, arm, mips64 and mips.
