Caitlin Potter 267115da42 [parser] avoid complex for-loop desugaring when possible 
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.
