[Interpreter] Introduce strict equality bytecode that does not collect feedback. Some of the StrictEquality comparisons do not require feedback (for ex: in try-finally, generators). This cl introduces StrictEqualityNoFeedback bytecode to be used in such cases. With this change, we no longer have to check if the type feedback slot is valid in compare bytecode handlers. This is the first step in reworking the compare bytecode handler to avoid duplicate checks when collecting feedback and when performing the operation.
