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.

by address.  This prevents the resultant SCEV objects from depending on
where in memory other scev objects happen to live.

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.
