Spread operator should be allowed anywhere in array literals and function calls

[BenoitZugmeyer]

Those statements should be valid:

var a = [...b, 1];
foo(...a, b, ...c);

Right now, running eslint on code like this gives me error Spread must be the final element of an element list and as it is a syntax error, it does not lint the file.

See MDN

Oops, must be confusing named function argument restrictions with other uses.

Working on this.
