    [intl] Remove redundant type checking system · 788c96a9
    littledan authored
    Previously, the Intl implementation tracked types two ways:
     - In the intl_initialized_marker_symbol
     - In various named properties of the intl_impl_object_symbol value
    
    As far as I can tell, these will never disagree with each other,
    modulo bugs in Intl itself. This patch removes the second type
    checking system.
    
    This reland includes a fixed type check for
    Intl.DateTimeFormat.prototype.formatToParts , which is the only Intl
    method which is not bound. All future methods will follow this
    pattern.
    
    The second reland ensures that a newly inserted test is only run
    if Intl is present.
