compiler, runtime: support and use single argument go:linkname

The gc compiler has started permitting go:linkname comments with a
single argument to mean that a function should be externally visible
outside the package.  Implement this in the Go frontend.

Change the libgo runtime package to use it, rather than repeating the
name just to export a function.

Remove a couple of unnecessary go:linkname comments on declarations.
