    [interpreter] Optimize strict equal boolean · 62632c08
    jameslahm authored
    For strict equal boolean literal like "a===true"
    or "a===false", we could generate TestReferenceEqual
    rather than TestStrictEqual. And in `execution_result()->IsTest()`
    case, we could directly emit JumpIfTrue/JumpIfFalse.
    
    E.g.
    ```
    a === true
    ```
    Generated Bytecode From:
    ```
    LdaGlobal
    Star1
    LdaTrue
    TestEqualStrict
    ```
    To:
    ```
    LdaGlobal
    Star1
    LdaTrue
    TestReferenceEqual
    ```
    
    E.g.
    ```
    if (a === true)
    ```
    Generated Bytecode From:
    ```
    LdaGlobal
    Star1
    LdaTrue
    TestEqualStrict
    JumpIfFalse
    ```
    To
    ```
    LdaGlobal
    JumpIfTrue
    Jump
    ```
