Previously, for the various customisation points of String builtins
(like String.prototype.replace), we skipped the customisation symbol
lookup (like for Symbol.replace) for Smis.
But, we do need to do the lookup for Smis in case Number.prototype or
Object.prototype have the Symbol. This missing lookup was creating an
observable difference between Smis and HeapNumbers.
