    Merge #838
    
    838: Add mssing mappings to HIR::Pattern r=philberty a=philberty
    
    These mappings are missing within the HIR but are required
    to complete typechecking of all patterns in match arms. As the
    fields of structures must bind their associated field's types to new
    names declared as part of the pattern, these mappings give access
    to the associated name-resolved NodeId's to figure this out.
