  Log Message:
  -----------
  [ConstantFold] Get rid of special cases for sizeof etc.

Target-dependent constant folding will fold these down to simple
constants (or at least, expressions that don't involve a GEP).  We don't
need heroics to try to optimize the form of the expression before that
happens.
