      Ignore the foreign_function_call_active flag on the x86 port. It was · c308db4d

      of no utility and wasn't even being maintained thoroughly. Can now use
      pseudo atomic in C code. All interrupt contexts are saved, even those
      that occur when running foreign C code; this may be necessary for
      reliable stack parsing on some operating systems, e.g. Linux.
      
      When the pending interrupt from a GC trigger is processed by
      interrupt_handle_pending, any other accumulated pending interrupt is
      also processed even if *interrupts-enabled* is false, breaking the
      behaviour of the *interrupts-enabled* flag.  The best way around this
      for the x86 port is to call maybe-gc directly from the allocation
      routines; remove the recently introduced function set_maybe_gc_pending
      which also had other problems. Note this problem will likely occur on
      the other ports.
