Rollup merge of #103034 - nathanwhit:let-chains-rhs-temporaries, r=wesleywiser
Let expressions on RHS shouldn't be terminating scopes Fixes #100276. Before this PR, we were unconditionally marking the RHS of short-circuiting binary expressions as a terminating scope. In the case of a let chain where the `let` expression was on the RHS, this meant that temporaries within the `let` expr would only live until the end of the expression. Since this only affected the RHS, this led to surprising behavior ([example](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=d1b0a5d1f01882f9c89c2194a75eb19f)). After this PR, we only mark the RHS as a terminating scope if it is not a `let` expression.
