    [heap] Introduce safepoint mechanism · 64759d44
    Dominik Inführ authored
    Add safepoint mechanism to stop concurrent threads and bring them to a
    safepoint. Threads are stopped before the safepoint and after e.g. the
    GC resumed again. Each thread needs to be stopped in a safepoint, such
    that all roots can be iterated safely.
    
    Running threads need to be cooperative and are required to perform
    regular safepoint polls.
    
    The last version of this CL was reverted because safepoint_requested_
    wasn't initialized (see https://crrev.com/c/2105634).
