Chris Lattner 82bec2cff0 Substantially refactor the SCCP class into an SCCP pass and an SCCPSolver 
class.  The only changes are minor:

 * Do not try to SCCP instructions that return void in the rewrite loop.
   This is silly and fool hardy, wasting a map lookup and adding an entry
   to the map which is never used.
 * If we decide something has an undefined value, rewrite it to undef,
   potentially leading to further simplications.
