    Add missing SMP symbols to RT linker.
    
    Summary:
    Add some missing symbols that we
    export from the public headers but forgot to include
    in the runtime linker's symbol table.
    
    This is a bit of a unsatifactory patch, since we have a bit of a
    cat and mouse game going. We should find a way to automate this.
    
    But I know of no good solutions at the moment that won't add all
    rts symbols (including those we don't have an extern declaration for.).
    
    So for now, just add the ones reported missing.
    
    Test Plan: inplace/bin/ghc-stage2.exe --interactive
