d4fef8dbca Implement shift-simplify.ll:test[45]. 
First teach instcombine that sign bit checks only demand the 
sign bit, this allows simplify demanded bits to hack on 
expressions better.

Second, teach instcombine that ashr is useless if only the
sign bit is demanded.

06205d5567 Implement shift-simplify.ll:test3, turning: 
(X << 31) <s 0  --> (X&1) != 0

This happens dozens of times in the CFE.
