    path solver: Merge path_range_query constructors.
    
    There's no need for two constructors, when we can do it all with one
    that defaults to the common behavior:
    
    path_range_query (bool resolve = true, gimple_ranger *ranger = NULL);
    
    Tested on x86-64 Linux.
    
    gcc/ChangeLog:
    
            * gimple-range-path.cc (path_range_query::path_range_query): Merge
            ctors.
            (path_range_query::import_p): Move from header file.
            (path_range_query::~path_range_query): Adjust for combined ctors.
            * gimple-range-path.h: Merge ctors.
            (path_range_query::import_p): Move to .cc file.
