History
Daniel Berlin af1954cd08 Update BasicAliasAnalysis to understand that nothing aliases with undef values. 
It got this in some cases (if one of them was an identified object), but not in all cases.

This caused stores to undef to block load-forwarding in some cases, etc.

Added test to Transforms/GVN to verify optimization occurs as expected.
