ab658f56a5 compiler: do simple deadcode elimination 
Normally the backend will do deadcode elimination and this is
    sufficient. However, the escape analysis operates on the AST that
    may have deadcode, and may cause things to escape that otherwise
    do not.
    
    This CL adds a simple deadcode elimination, run before the escape
    analysis.

ffaa3a1c74 go/internal/gccgoimporter: ignore unexported and imported names 
Due to inlining, we can now see unexported functions and variables,
    and functions and variables imported from different packages.
    Ignore them rather than reporting them from this package.
    
    Handle $hash and $equal functions consistently, so that we discard the
    inline body if there is one.
    
    Ignore names created for result parameters for inlining purposes.
