[JSC] Implement atomic operations in new wasm baseline JIT
https://bugs.webkit.org/show_bug.cgi?id=252457
rdar://105581013
Reviewed by Justin Michaud.
This patch implements atomics in new wasm baseline JIT. And it also fixes some
issues.
1. Implement all wasm atomics in new wasm baseline JIT.
2. We found that new baseline's emitCCall's results are wrong since C-Call and
Wasm-Call have difference in calling convention,
in particular, return values. We, for now, fix the return values. We should
decouple Wasm-Call calling convention things from
emitCCall since this is C-Call.
3. Fix disassembly conditions.
4. Show AssemblyComments when needDisassemblySupport is true.
