[JSC] Move symbolHasInstance to C++
https://bugs.webkit.org/show_bug.cgi?id=313401
rdar://175659837
Reviewed by Yijia Huang.
This patch moves symbolHasInstance implementation to C++ as this
function is no longer called from the normal path as instanceof
is having special optimized path skipping this call. So it is used only
when we explicitly call this function, which is extremely rare.
