8918461fc4 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

e2f1049bd5 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).

New snapshot means this can all go. Also removes places that have
comments that say they are workarounds for stage0 errors.

301f9001c0 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.

12203a76c2 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.

4af2d90af5 add an option to debug borrows (RUST_DEBUG_BORROW) so you can
find out where the offending borrow occurred. This ... still needs
some work.

People hit the recursion depth limit too often, it's not possible
to unwind reliably from out-of-stack.

in the new scheduler, for now at least, and I don't have a rust_env
available.
