673e02b0c3 This nutty patch has been in my tree since before 1.3 went out, and it needs 
to go in.  This patch allows us to compute the trip count of loops controlled
by values loaded from constant arrays.  The cannonnical example of this is
strlen when passed a constant argument:

for (int i = 0; "constantstring"[i]; ++i) ;
return i;

In this case, it will compute that the loop executes 14 times, which means
that the exit value of i is 14.  Because of this, the loop gets DCE'd and
we are happy.  This also applies to anything that does similar things, e.g.
loops like this:

  const float Array[] = { 0.1, 2.1, 3.2, 23.21 };
  for (int i = 0; Array[i] < 20; ++i)

and is actually fairly general.

The problem with this is that it almost never triggers.  The reason is that
we run indvars and the loop optimizer only at compile time, which is before
things like strlen and strcpy have been inlined into the program from libc.
Because of this, it almost never is used (it triggers twice in specint2k).

I'm committing it because it DOES work, may be useful in the future, and
doesn't slow us down at all.  If/when we start running the loop optimizer
at link-time (-O4?) this will be very nice indeed :)

from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

efffdc9408 As much as I hate to say it, the whole setNode interface for DSNodeHandles 
is HOPELESSLY broken.  The problem is that the embedded getNode call can
change the offset of the node handle in unpredictable ways.

As it turns out, all of the clients of this method really want to set
both the node and the offset, thus it is more efficient (and less buggy)
to just do both of them in one method call.  This fixes some obscure bugs
handling non-forwarded node handles.

3b04a8ac45 Initial checkin of a simple mod/ref analysis for global variables. This is 
still overly conservative and uses very simple data structures, but it is a
start, and allows elimination of a lot of loads.

c5204fb6f8 Complete rewrite of the code that merges DS graphs for equivalence classes 
of functions called at a common call site.  The rewrite inlines the
resulting graphs bottom-up on the SCCs of the CBU call graph.  It also
simplifies the merging of equivalence classes by exploiting the fact that
functions in non-trivial SCCs are already merged.

6178085cfd Move the stuff that fixes the size, orientation & fonts of graphs to 
the debugging functions that call "dot". These fixed settings have
various problems: for example, the fixed size that is set in the graph
traits classes is not appropriate for turning the dot file into a PNG,
and if TrueType font rendering is being used, the 'Courier' TrueType font
may not be installed. It seems easy enough to specify these things on the
command line, anyhow.
