The "use RB_GC_GUARD instead" advice can be unsought. People might not understand why they should use RB_GC_GUARD instead of it. In fact they don't have to, unless they are Eric Wong. It seems nobody except Eric could be creative enough to abuse this function as a GC guard.

That's a good point. I've updated the message to not include that suggestion.
This commit removes usages of rb_gc_force_recycle since it is a burden to maintain and makes changes to the GC difficult.

Good catch. I don't think it's needed.

…mark_stack_chunk This commit deprecates rb_gc_force_recycle and coverts it to a no-op function. Also removes invalidate_mark_stack_chunk since only rb_gc_force_recycle uses it.

I'm proposing to deprecate
rb_gc_force_recycleand make it a no-op function because it is a burden to maintain and makes changes to the GC difficult. It is also easy to incorrectly use this function and cause memory leaks such as #18065.
