compiler: compare parse methods when indexing interface types for export
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.

compiler: add new debugging helper function debug_go_type()
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:

This patch set adds new pipeline descriptions for z13 and z14. Based

The patch before (r269620) also belongs to this set but I accidentally
applied it separately.

Use libiberty's lrealpath to avoid portability problems.
The dmd front-end function FileName::canonicalName could be called
during the semantic pass of import("file") expressions, so still
requires that realpath() be redefined.
