Destructing statements that start off as declarations can end up becoming reassignments if the variable is a scope declaration, so we have existing logic to handle cases where some parts of a destructure need to be converted into new locals, with a reassignment to the hoisted scope variable afterwards. However, there is an edge case where all of the values are reassigned, in which case we don't need to rewrite and can just set the instruction kind to reassign.
The next PR needs to check if a block is controlled by a value derived from a ref.

…conditionals Conditionally calling setState in an effect is sometimes necessary, but should generally follow the pattern of using a "previous vaue" ref to manually compare and ensure that the setState is idempotent. See fixture for an example.
