David Majnemer 5939f08f5e InstCombine: Don't unconditionally preserve 'nuw' when shrinking constants 
Consider:
  %add = add nuw i32 %a, -16777216
  %and = and i32 %add, 255

Regardless of whether or not we demand the sign bit of %add, we cannot
replace -16777216 with 2130706432 without also removing 'nuw' from the
instruction.

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
