Once the vm-service isolate starts up it will iterate over all isolates
to discover already started isolates. It does so via iterating over all
isolate groups and all isolates within them. Doing so requires a read
lock.
Until now it has called into Dart while holding the read lock. This can
lead to a deadlock, since calling Dart code can trigger JIT compilation
which can trigger various things that require the same lock.
Instead, this CL accumulates a list of (isolate-main-port, isolate-name)
pairs while iterating over isolate groups and the isolates therein.
Afterwards it registers those isolates in a bulk - without holding any
locks.

When these were originally added, we thought we would be able to use them in place of ifdefs and rely on the compiler optimizations and linker GC to remove things. This turned out not to reliably remove what we wanted removed, so we ended up with the ifdefs anyway.

Threads in the native or blocked states don't prevent safepoints, so they may run concurrently with a safepoint operation like GC. It is not safe for handles to be allocated while the GC is visiting them, so these threads must not allocate handles. Assert only threads in the VM or generated states, which prevent safepoints until they check in, may allocate handles. (Generated code does not allocate handles, but leaf runtime entries remain in the generated state.)

- uses a per thread safepoint handshake between the thread requesting a safepoint and the requested thread.
