Fix start_world not resuming all threads on Darwin
Issue #231 (bdwgc).
This happens due mach thread ports are released in GC_stop_world as
a result in some cases the system creates new one and GC_start_world
will not find the thread to resume; in turn, the threads will stay
suspended. When this happens to GDC threads, the application is
terminated as the message loop is halt.
The high-level description of the change: thread mach port is not
deallocated when thread is saved in GC_mach_threads as it causes thread
not being resumed as thread port object can be changed; threads are now
being suspended without check of suspend_count (as it can be suspended
by client); the logic of resume is changed, now the primary cycle
iterates threads to resume in GC_mach_threads.
