libgo patch committed: Remove closedchan function

[Ian Lance Taylor]

With the removal of the predeclared function 'closed' from Go, and the
update to the current Go library, the 'closedchan' function is no longer
needed.  This patch removes it from libgo.  Bootstrapped and ran Go
testsuite on x86_64-unknown-linux-gnu.  Committed to mainline.
