intersecting bits. This triggers all over the place, for example in lencode, with adds of stuff like: %tmp580 = mul i32 %tmp579, 2 %tmp582 = and i32 %b8, 1 and %tmp28 = shl i32 %abs.i, 1 %sign.0 = select i1 %tmp23, i32 1, i32 0 and %tmp344 = shl i32 %tmp343, 2 %tmp346 = and i32 %tmp96, 3 etc. llvm-svn: 51263
