Also, we now use a separate globals graph to hold externally visible nodes.
This changes both the bottom-up and top-down propagation so that
globals and other external objects do not have to appear in every
function, but only in functions in which they are referenced or
they can be used to access something else that is referenced.

Cleanup ConstantExpr handling:
 * Correctly delete TypeHandles in AsmParser.  In addition to not leaking
   memory, this prevents a bug that could have occurred when a type got
   resolved that the constexpr was using
 * Check for errors in the AsmParser instead of hitting assertion failures
   deep in the code
 * Simplify the interface to the ConstantExpr class, removing unneccesary
   parameters to the ::get* methods.
 * Rename the 'getelementptr' version of ConstantExpr::get to
   ConstantExpr::getGetElementPtr

* 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.

  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.
