Log:
    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.
