In https://chromium-review.googlesource.com/c/472247/, I avoided running DesugarLexicalBindingsInForStatement() if there were no lexical loop variables, the function was not resumable, and the variables are not captured by eval or a function declaration. I think it's now possible to limit this further, and only do the more extensive desugaring if there's a function declaration / eval() call in the loop body. `yield` and `await` are not an issue as those loop variables are written to the register file and not lost. This change just removes the `is_resumable()` condition. If it passes tests, I think it's safe.
