vm_core.h (typedef struct rb_vm_struct): create a new
'inhibit_thread_createion' field.
thread.c (rb_thread_terminate_all): set inhibit_thread_creation.
thread.c (thread_s_new): don't permit to create new thread
if the VM is under destruction. Otherwise evil finalizer code
can make SEGV. [Bug #4992][ruby-core:37858]
bootstraptest/test_objectspace.rb: new test for this fix.
