This commit removes the `#[cfg]` guards in `atomic::fence` on wasm
targets. Since these guards were originally added the upstream wasm
specification for threads gained an `atomic.fence` instruction, so LLVM
no longer panics on these intrinsics.

Although there aren't a ton of tests in-repo for this right now I've
tested locally and all of these fences generate `atomic.fence`
instructions in wasm.

Closes rust-lang#72997

Given a code

```rust
fn foo(x: u8, y: u32) -> bool {
    x > y
}
fn main() {}
```

it could be more helpful to provide a suggestion to do "u32::from(x)"
rather than "y.try_into().unwrap()", since the latter may panic.

We do this by passing the LHS of a binary expression up the stack into
the coercion checker.

Now there are instructions on how to convert back and forth on both
structs, not just one.

Fix #[thread_local] statics as asm! sym operands

The `asm!` RFC specifies that `#[thread_local]` statics may be used as `sym` operands for inline assembly.

This also fixes a regression in the handling of `#[thread_local]` during monomorphization which caused link-time errors with multiple codegen units, most likely introduced by rust-lang#71192.

std: Enable atomic.fence emission on wasm32

Add various Zulip notifications for prioritization

Adapts `triagebot.toml` for rust-lang/triagebot#616 and adds various Zulip notifications for the Prioritization WG workflow.
We should also add indications about the procedure for handling those events, cc @rust-lang/wg-prioritization.

This should be merged as soon as possible after rust-lang/triagebot#616 is merged, cc @Mark-Simulacrum
