[JSC] Fix wasm table / memory operation conditions in new wasm BBQ
https://bugs.webkit.org/show_bug.cgi?id=252528
rdar://105627708
Reviewed by Mark Lam.
1. Fix wasm table / memory operation conditions. We should use branchTest32
instead of branchTest64 to test exception condition.
We also use UCPUStrictInt32 to ensure that return GPR is clearing the upper
bits too.
2. Fix frame size rounding code.
3. Move emitEntryTierUpCheck place since it can clobber some argument registers.
4. Fix some more conditions about AssemblyComments.
