no semicolon after var/let/const does not allow expression on next line

[danez]

function a() {
  let x
  /asd/g
}

or with jsx

function a() {
  let x
  <asd />
}

both should work as ASI is supposed to add a semicolon after the variable declaration.

Chrome parses the first one correctly.

Tried with acorn 6.0.2

Related to #589 (again). This one actually seems really hard to address with the current stand-alone-tokenizer approach

[marijnh]

Attached patch should address this for regular expressions (and probably all further issues in this class). Could you open a separate issue on acorn-jsx? This approach won't help there—the tokenizer doesn't know an expression is coming up in this situation, so that plugin will need a similar kludge.
