Bug: let followed by a new line fails

[galvez]

Snippet in question:

function foo () {
  let
    bar
  bar = 1
  return bar
}

Error:

Module parse failed: The keyword 'let' is reserved

Interesting. This behaves like this in esbuild because it's necessary to be able to pass test262 conformance tests like this one. But it looks like perhaps these ASI rules should only apply in a single-statement context. I will fix this in the next release.
