[Errors] error recovery with illegal modifiers inside function bodies

[mhegazy]

export function foo() {
       export var x = this;    
}

Expected:

!!! Modifiers cannot appear here.

Actual:

    export function foo() {
       export var x = this;
!!! Statement expected.
    }
!!! Declaration or statement expected.
