[JSC] Fix restoreWebAssemblyGlobalState in new wasm baseline JIT
https://bugs.webkit.org/show_bug.cgi?id=252503
rdar://105611063
Reviewed by Justin Michaud.
cageConditionallyAndUntag cannot take m_dataScratchGPR for multiple scratch
registers. They need different one.
This patch changes the new wasm baseline JIT to always reserve
GPRInfo::wasmBoundsCheckingSizeRegister.
We anyway reserving all callee-save registers right now, so it does not change
the code generation. Plus, this
makes implementation simpler.
