[Gc] Changes for darwin GC_push_all_stacks

[Ivan Maidanski]

Hi!

In darwin GC_push_all_stacks (both variants), I've removed pushing segment selectors, flags, eip/__pc and esp registers (but added ebp pushing).

Also, I've made thread_state_count/outCount to be reset to GC_MACH_THREAD_STATE_COUNT (not to THREAD_STATE_MAX) on every thread_get_state() call.

Would be nice if some MacOS users review the patch and run testing.

Regards.
