Add VM_ASSERT on `fiber->blocking == 0`. (#7926) 
I have not seen any problems with this code, but this ensures the invariant.

Assigning `nil` to fiber storage deletes the association. (#7378) 
Also avoid allocations when looking up `Fiber#storage` if not needed.

YJIT: GC and recompile all code pages (#6406)

MJIT: Stop using the VM barrier for jit_cont 
This solves multiple problems.

First, RB_VM_LOCK_ENTER/LEAVE is a barrier. We could at least use the
_NO_BARRIER variant.

Second, this doesn't need to interfere with GC or other GVL users when
multiple Ractors are used. This needs to be used in very few places, so
the benefit of fine-grained locking would outweigh its small maintenance
cost.

Third, it fixes a crash for YJIT. Because YJIT is never disabled until a
process exits unlike MJIT that finishes earlier, we could call jit_cont_free
when EC no longer exists, which crashes RB_VM_LOCK_ENTER.

Peter Zhu efb91ff19b Rename rb_ary_tmp_new to rb_ary_hidden_new 
rb_ary_tmp_new suggests that the array is temporary in some way, but
that's not true, it just creates an array that's hidden and not on the
transient heap. This commit renames it to rb_ary_hidden_new.

Aaron Patterson 1341dea771 Prevent the stack from being marked twice 
This commit prevents the stack from being marked twice: once via the
Fiber, and once via the Thread.  It introduces an assertion to assert
that the ec on the thread is the same as the ec on the Fiber being
marked via the thread.

Yusuke Endoh 5060c9d852 cont.c: prevent a warning of GCC 12.1 
... by assigning a dummy value to the allocated stack.

http://rubyci.s3.amazonaws.com/arch/ruby-master/log/20220613T000004Z.log.html.gz
```
cont.c: In function ‘cont_restore_0.constprop’:

Also it adds some comments about the hack of dummy stack allocation.

`rb_fiber_terminate` must not return [Bug #18497] 
In a forked process from a fiber, the fiber becomes the only
fiber, `fiber_switch` does nothing as there is no other fibers,
`rb_fiber_terminate` does not terminate the fiber.  In that case,
reaches the end of `fiber_entry` finaly, which is declared as
"COROUTINE" and should never return.
