libgo patch committed: Update to weekly.2012-01-20

[Ian Lance Taylor <iant at google dot com>]

I have committed a patch to libgo to update to the weekly.2012-01-20
release.  As usual this e-mail message only includes changes to files
specific to gccgo.  Bootstrapped and ran Go testsuite on
x86_64-unknown-linux-gnu.  Committed to mainline.

Ian
