Update wasm threads proposal tests and fix cmpxchg_u (edited)
https://bugs.webkit.org/show_bug.cgi?id=263292
rdar://117102231
Reviewed by Justin Michaud and Yusuke Suzuki.
In https://github.com/WebAssembly/threads/issues/195, it was documented
that JSC implements cmpxchg_u without wrapping the expected value.
Previously, the spec tests and reference interpreter followed this
interpretation,
but the spec text, SpiderMonkey and v8 did the wrapping.
The spec tests were updated, and this new behaviour is simpler anyway,
so let's just do it.
