let/const declarations in "standard" C-style for-loops have some complex desugaring to accommodate the case where loop loop variables may be captured. This slows down the baseline performance of for-loops with let variables. This change attempts to avoid this desugaring if it's known that the loop variable is not captured at any point. A side effect of this change is that let/const loop variables, when not captured within the loop body, are not necessarily shown in the debugger, similar to other stack-allocated vars.
