Reducing the number of GC roots can be a positive thing but I don't expect much difference in this regard, considering we don't normally create that many WeakReference internally anyway (unless the user uses domain heavily, but domain has long been deprecated) |

Previously we assume that the objects are GC'ed after one global.gc() returns, which is not necessarily always the case. Use gcUntil() to run GC multiple times if they are not GC'ed in the first time around.
The C++ implementation can now be done entirely in JS using WeakRef. Re-implement it in JS instead to simplify the code.
