Ben Alpert ff8a10e52f Add option to block-scoping to slow on throw code (#5236)
The let/const plugin can add closures where you don't expect them. This is undesirable in some perf-sensitive projects (ex: React). I added an option that throws whenever the plugin adds a function (as opposed to simply renaming variables when converting to var).
