The source position is set to the function call (console.log) not the
spread (..x), in the bytecode generator, as the spread operation is
done as part of the CallWithSpread bytecode.
The CallPrinter stops at the function call and doesn't look at the
arguments as well (in CallPrinter::VisitCall) to see if the error is
from an incorrect spread operation.
With this patch, we pass some state to the CallPrinter in the
CallWithSpread error case and check that in CallPrinter::VisitCall
before returning.
For the given source string:
```
x = undefined;
console.log(1, ...x);
```
Previously, the error was -
```
test.js:2: TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))
console.log(1, ...x);
^
TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator))
at test.js:2:9
```
Now, the error is -
```
_test.js:2: TypeError: x is not iterable (cannot read property undefined)
console.log(1, ...x);
^
TypeError: x is not iterable (cannot read property undefined)
at _test.js:2:9
```
