Alexandre Ganea 7b25fa8c7a [Support] Attempt to fix deadlock in ThreadGroup 
This is an attempt to fix the situation described by https://reviews.llvm.org/D104207#2826290 and PR41508.
See sequence of operations leading to the bug in https://reviews.llvm.org/D104207#3004689

We ensure that the Latch is completely "free" before decrementing the number of TaskGroupInstances.
