…cupiver std: make `thread::current` available in all `thread_local!` destructors ... and thereby allow the panic runtime to always print the right thread name. This works by modifying the TLS destructor system to schedule a runtime cleanup function after all other TLS destructors registered by `std` have run. Unfortunately, this doesn't affect foreign TLS destructors, `thread::current` will still panic there. Additionally, the thread ID returned by `current_id` will now always be available, even inside the global allocator, and will not change during the lifetime of one thread (this was previously the case with key-based TLS). The mechanisms I added for this (`local_pointer` and `thread_cleanup`) will also allow finally fixing rust-lang#111272 by moving the signal stack to a similar runtime-cleanup TLS variable.

Fixes rust-lang#111272. With rust-lang#127912 merged, we now have all the infrastructure in place to support stack overflow detection in TLS destructors. This was not possible before because the signal stack was freed in the thread main function, thus a SIGSEGV afterwards would immediately crash. And on platforms without native TLS, the guard page address was stored in an allocation freed in a TLS destructor, so would not be available. rust-lang#127912 introduced the `local_pointer` macro which allows storing a pointer-sized TLS variable without allocation and the `thread_cleanup` runtime function which is called after all other code managed by the Rust runtime. This PR simply moves the signal stack cleanup to the end of `thread_cleanup` and uses `local_pointer` to store every necessary variable. And so, everything run under the Rust runtime is now properly protected against stack overflows.

Fixes rust-lang#111272. With rust-lang#127912 merged, we now have all the infrastructure in place to support stack overflow detection in TLS destructors. This was not possible before because the signal stack was freed in the thread main function, thus a SIGSEGV afterwards would immediately crash. And on platforms without native TLS, the guard page address was stored in an allocation freed in a TLS destructor, so would not be available. rust-lang#127912 introduced the `local_pointer` macro which allows storing a pointer-sized TLS variable without allocation and the `thread_cleanup` runtime function which is called after all other code managed by the Rust runtime. This PR simply moves the signal stack cleanup to the end of `thread_cleanup` and uses `local_pointer` to store every necessary variable. And so, everything run under the Rust runtime is now properly protected against stack overflows.

... and thereby allow the panic runtime to always print the right thread name.
This works by modifying the TLS destructor system to schedule a runtime cleanup function after all other TLS destructors registered by
stdhave run. Unfortunately, this doesn't affect foreign TLS destructors,thread::currentwill still panic there.Additionally, the thread ID returned by
current_idwill now always be available, even inside the global allocator, and will not change during the lifetime of one thread (this was previously the case with key-based TLS).The mechanisms I added for this (
local_pointerandthread_cleanup) will also allow finally fixing #111272 by moving the signal stack to a similar runtime-cleanup TLS variable.
