 1. Calls to external global VARIABLES should not be treated as a call to an
    external function
 2. Efficiently deleting an element from a vector by using std::swap with
    the back, then pop_back is NOT a good way to keep the vector sorted.
 3. Our hope of having stuff get deleted by making them redundant just won't
    work.  In particular, if we have three calls in sequence that should be
    merged: A, B, C   first we unify B into A.  To be sure that they appeared
    identical (so B would be erased) we set B = A.  On the next step, we
    unified C into A and set C = A.  Unfortunately, this is no guarantee that
    C = B, so we would fail to delete the dead call.  Switch to a more
    explicit scheme.

* change some uses of NH.getNode() in a bool context to use !NH.isNull()
* Fix a bunch of places where we depended on the (undefined) order of
  evaluation of arguments to function calls to ensure that getNode() was
  called before getOffset().  In practice, this was NOT happening.

Fixed issue with generating the partial order. It now adds the nodes not in recurrences in sets for each connected component.

sub-makes and recursively append causing huge command lines and incorrect
compilation results.

Also, fix the printvars target to align its output and ensure that the
contents of variables can't get interpreted by the shell.

It is left in place in case anyone wants to updated it for GCC 3.4 or
re-use it for earlier versions of GCC where it works.

This is still probably not correct, or portable, but it'll do for now.

* Move rules that build directories earlier in the file so that they are
  always built before the things that depend on them. This enables a
  parallel "dist-check" target.
* Fix use of TOOLLINKOPTS and TOOLLINKOPTSB (thanks to Henrik Bach)
* Standardize the output - some scripts using plain echo instead of $(ECHO)
