Go patch committed: Don't call cgraph_mark_needed_node

[Ian Lance Taylor]

Honza removed the function cgraph_mark_needed_node from mainline.  The
Go frontend called it, but that call was left over from days long ago
when package initialization was run as a global constructor.  Package
initialization is now done by a direct call from the main function
(found in libgo/runtime/go-main.c), so the function is no longer special
from a cgraph point of view.  This patch just removes the call to
cgraph_mark_needed_node.  Bootstrapped and ran Go testsuite on
x86_64-unknown-linx-gnu.  Committed to mainline.
