Bug 224964 – [JSC][Win] callOperationNoExceptionCheck() also needs to support operations that return SlowPathReturnType

[JSC][Win] callOperationNoExceptionCheck() also needs to support operations that return SlowPathReturnType

r276456 started to use callOperationNoExceptionCheck instead of
callOperation. It made Windows ports crashing.

Bug 183655 added special support for x64 Windows. But, it added
only for callOperation, but for callOperationNoExceptionCheck.
callOperationNoExceptionCheck also should support x64 Windows.

Bug 183655 – JIT callOperation() needs to support operations that return SlowPathReturnType differently on Windows.
Bug 224920 – [JSC] Remove exception checks from non-throwing function calls in Baseline JIT
Bug 224952 – REGRESSION(r276456): Windows specific crash

Use static constexpr instead of static const

I don't know what the problem is. I should try rewriting the patch without constexpr if.

Patch

[Fujii Hironori]

I downgraded my Visual Studio 2019 to version 16.3 on my PC. This internal compiler problem is caused by the template variable.
I rewrote the patch without the template variable.
