Go patch committed: Add debugging helper function debug_go_type

[Ian Lance Taylor <iant at golang dot org>]

This patch to the Go frontend by Than McIntosh adds a new debugging
helper function debug_go_type.  This is 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.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.
