* Implement stuff so that code can declare that they only depend on the CFG of
  a function, not on anything else.  This speeds up GCCAS a lot.

Implement constant propogation of logical (and, or, xor) expressions.

* Object orientize the functions, cleanup code a bit.  Instead of static
  global functions, the helpers for instruction selection are now part of
  the InstructionSelection Pass class.

  which was caused by us not running the "drop references of dead
  instructions" code when there were no basic blocks that were dead.

  We still don't want to do some of the stuff we do if there are dead
  basic blocks, but we DO want to drop references of dead instructions,
  so we factor the common code out to a new method.

* Simplify how AnalysisID's are initialized
* Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into
