Chris Lattner ead0d88ad7 add a new -enable-value-prop flag for llcbeta, that enables propagation ...

of value info (sign/zero ext info) from one MBB to another.  This doesn't
handle much right now because of two limitations:

1) only handles zext/sext, not random bit propagation (no assert exists 
   for this)
2) doesn't handle phis.
