Go patch committed: Update libgo to Go release r60

[Ian Lance Taylor]

I've committed a patch to mainline which updates libgo to the version in
the Go r60 release.  I haven't appended all the changes here, as they
are too large, and in any case most of them are just copied directly
from the master Go library repository.  I have only appended the changes
to files which are not directly copied.  Bootstrapped and ran Go
testsuite on x86_64-unknown-linux-gnu.  Committed to mainline.

History shows that Go library updates sometimes break the Go build on
non-GNU/Linux targets.  I tried to be careful this time, but please let
me know about any new problems.

Ian
