Owen Anderson be80240b29 Add partial redundancy elimination.

Owen Anderson ddbe430732 Fix a misunderstanding of the algorithm. Really, we should be tracking values 
and expression separately.  We can get around this, however, by only keeping
opaque values in TMP_GEN.

Owen Anderson 9b89e4b561 Fix a small bug, some 80 cols violations, and add some more debugging output.

Owen Anderson 3c9d8eef21 Don't use std::set_difference when the two sets are sorted differently. Compute 
the difference manually instead.

This allows GVNPRE to produce correct analysis for the example in the GVNPRE
paper.

Owen Anderson 0b68cda302 There's no need to have an Expression class... Value works just as well! This simplifies a lot of code.

Owen Anderson 48e93f2ce9 clean() needs to process things in topological order.

Owen Anderson 4c89142466 Fix Expression comparison, which in turn fixes a value numbering error.

Owen Anderson 4a6ec8fb57 Use proper debugging facilities so other people don't have to look at my commented-out 
debugging lines.

Owen Anderson f11bdc7637 Comment debug code out that I accidentally uncommented last time.

Owen Anderson ac83a3e4ff Add a place where I missed using the maximal set. Note that using the maximal 
set this way is _SLOW_.  Somewhere down the line, I'll look at speeding it up.

Owen Anderson 5fba6c19b2 Very first part of a GVN-PRE implementation. It currently performs a bunch of analysis, and nothing more. It is also quite slow for the moment. However, 
it should give a sense of what's going on.
