compiler: permit inlining references to global variables

    
    This requires tracking all references to unexported variables, so that
    we can make them global symbols in the object file, and can export
    them so that other compilations can see the right definition for their
    own inline bodies.
    
    This introduces a syntax for referencing names defined in other
    packages: a <pNN> prefix, where NN is the package index.  This will
    need to be added to gccgoimporter, but I didn't do it yet since it
    isn't yet possible to create an object for which gccgoimporter will
    see a <pNN> prefix.
    
    This increases the number of inlinable functions in the standard
    library from 181 to 215, adding functions like context.Background.
