Emit more efficient 64-bit operations when the RHS is a constant, and one of the words of the constant is zeros. For example: Y = and long X, 1234 now generates: Yl = and Xl, 1234 Yh = 0 instead of: Yl = and Xl, 1234 Yh = and Xh, 0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12685 91177308-0d34-0410-b5e6-96231b3b80d8
