Chris Lattner b9a7793ecb Avoid creating 'load X, 0' instead of just 'load X'

This _trivial_ change causes GCSE and LICM to be much more effective at
hoisting loads.  Before it would not be able to eliminate 'load X' if there
was just a dominating 'load X, 0' because the expressions were not identical.
