1898041 - Expand test coverage of wasm code on suspendable stacks

Status: NEW

(Core :: JavaScript: WebAssembly, task, P3)

Description

[Ryan Hunt [:rhunt]]

It'd nice to expand the coverage of wasm features running on a suspendable stack.

At a minimum we should probably have:

1. GC allocation
2. GC collection
3. Stack overflows
4. Traps
5. Atomic waits

It's a little unfortunate to duplicate a lot of the tests we already have, just with them running on a different stack. It'd be neat if we could have a mode where wasm code always runs on a separate stack transparently to increase test coverage without writing new tests. I did something like this for multi-memory, but didn't have a good way to land it.
