    This change fixes a bug in which two interface types were being
    incorrectly commoned (considered identical) in the initial stages of
    writing out types to export data. The indexer does a walk to collect
    candidates for export, inserting types into a table to eliminate
    duplicates; as part of this process a local interface type T1 was
    being commoned with a different interface type T2. This caused a cycle
    in the exported type graph due to the way embedded interfaces are
    handled.
    
    The fix was to add a new flag to the Type::is_identical utility
    routine to request that interface type comparison be done by examining
    the original parse methods, as opposed to the expanded method set,
    then use the new flag when creating the hash map for the exporter.
    
    Fixes golang/go#30659.

    Add a new debugging utility routine debug_go_type(), intended to
    display the contents of a Type object in a way useful to debugging
    a run of the compiler.  Prior to this the only useful alternative
    for debugging types was invoking the mangled_name() method, which
    has problems (for example, won't work on interface types prior
    to finalizing of methods).
    
    This is a "deep" dump, meaning that all types reachable from the
    type passed to debug_go_type() will be printed out. Example:
    
    (gdb) print debug_go_type(t1)
          T0        0x535f300  'net/http.Header' -> T1
          T1        0x535d3d0  map ['string' -> string] T4
          T2        0x5304bb0  'string' -> string
          T3        0x331f900  string
          T4        0x535d370  array [] 'string' -> string

This patch set adds new pipeline descriptions for z13 and z14.  Based
on that, the scoring and some properties are handled differently in
