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

  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.
