Chris Lattner 26dff501a4 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.

Chris Lattner eb3e84078d Do not sort SCEV objects by address: instead sort by complexity and group 
by address.  This prevents the resultant SCEV objects from depending on
where in memory other scev objects happen to live.

Chris Lattner feda9d0583 Fix a tiny bug in the -no-aa pass, in which it did not ever get a target data. 
This is a regression from 1.2, though noone uses -no-aa anyway

Brian Gaeke e330adf842 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.
