Change the ranlib detection On Windows, the ranlib in the path may not be the right ranlib (it may be the 32bit ranlib when we are making a Win64 compiler, or vice-versa). Therefore we can't leave it up to libffi to detect the right ranlib, but need to tell it which ranlib to use. This means that we need to find ranlib even if we don't actually need it ourselves.

Fix #7970, #2161, unfix #551 Establish the reachability of threads before weak pointers. Hence a deadlocked thread can keep a weak pointer alive and prevent it from being finalized early. However, an reference from the finalizer of a weak pointer will no longer prevent a thread from being considered deadlocked (#551). To keep the thread alive in that situation you need to use a StablePtr. See comments on #7970 and in the code for more details.
