Bug 255508 – LLInt should update stackTraceLimit in GlobalObject

• Status: NEW
• Component: JavaScriptCore

[EntryHi]

function f0(a1) {
  try{
    Error.stackTraceLimit = a1; // put_by_id
    throw Error()
  }
  catch(e)
  {
    return e.stack;
  }
}
for (let v14 = 0; v14 < 2; v14++) {
  print(f0(v14));
}

With the above script as input to JSC, run JSC with the following parameters:
./jsc test.js --useConcurrentJIT=0 

JSC print two "undefined". The corrent result should be an "undefined" and a stackTrace. The problem may be in LLInt. 

The number of loops is 2. Therefore, LLInt will execute `put_by_id` twice, the first execution is slow_path, and `stackTraceLimit` in `globalObject` will be updated, but the slow_path is not used for the second time, and `stackTraceLimit` in `globalObject` is not updated. `getStackTrace` in Error.cpp will use `stackTraceLimit`, but stackTraceLimit is always 0, so two "undefined" are printed. 

Safari console also prints wrong result, V8 prints correct result.
