Bug Report

Current Behavior
The code yield new Foo() results in a syntax error:

SyntaxError: Unexpected token, expected ";" 

Input Code

export function* test() {
  yield new Foo();
}

Expected behavior/code
I expect this valid code to parse successfully.

Babel Configuration (.babelrc, package.json, cli command)
This will fail with no configuration (ie. the default). I've also tried a few different combinations of presets/plugins to get this work but it always fails.

Environment

• Babel version(s): @babel/cli v7.2.0, @babel/parser v7.3.0
• Node/npm version: Node.js v11.6.0, NPM 6.6.0
• OS: MacOS 10.14.2
• Monorepo: no
• How you are using Babel: cli
