[JSC] Improve error message for calling constructor without `new`
https://bugs.webkit.org/show_bug.cgi?id=298927
Reviewed by Yusuke Suzuki.
Calling constructors without `new` is invalid:
class Foo {}
Foo();
Current JSC throws a TypeError with the message "Cannot call a class
constructor without |new|" for such code.
This patch changes this error message to include the constructor name
for debugging experience.
