Andreas Kling bc21ed151e LibJS/Bytecode: Handle awkward initialization case for duplicate var ...

`var` declarations can have duplicates, but duplicate `let` or `const`
bindings are a syntax error.

Because of this, we can sink `let` and `const` directly into the
preferred_dst if available. This is not safe for `var` since the
preferred_dst may be used in the initializer.

This patch fixes the issue by simply skipping the preferred_dst
optimization for `var` declarations.
