    Merge #879
    
    879: Record correct location when compiling ADT types r=philberty a=dafaust
    
    When compiling struct and union types, we were using the wrong HirId
    to lookup location information. The resulting GIMPLE nodes therefore
    had no source location information, which made them indistinguishable
    as user-declarations versus decls created by the compiler. As a result,
    the type names were not shown in GIMPLE dumps, e.g. using
    -fdump-tree-gimple.
    
    Fix the location lookup, so these types are properly printed, and add a
    simple test checking as much.
    
    Fixes: #877
