rt: Release big stacks immediately after use to avoid holding on to them through yields
...
This avoids the following pathological scenario that makes threadring OOM:
1) task calls C using fast_ffi, borrowing a big stack from the scheduler.
2) task returns from C and places the big stack on the task-local stack segment list
3) task calls further Rust functions that require growing the stack, and for this reuses the big stack
4) task yields, failing to return the big stack to the scheduler.
5) repeat 500+ times and OOM

Remove unused TyDesc parameter from the glue functions

To remove the environment pointer, support for function pointers without
an environment argument is needed (i.e. a fixed version of #6661 ).

Assert stk rather than checking null
...
Given that a big stack is never requested before allocating an initial
stack segment, having a non-null stk member here is an invariant.

Check stk before dereferencing
...
This commit fixes #7022 - I've added an additional check to ensure that
stk is not null before dereferencing it to get it's next element,
assigning NULL if it is itself NULL.
