  [X86] Custom legalize v1i1 add/sub/mul to xor/xor/and with avx512.

We already did this for v2i1, v4i1, v8i1, etc.

  Log Message:
  -----------
  [X86] Fix a couple copy mistakes in v4i1 or/and/xor isel patterns.

VK1 was being used as the output of the copy to regclass, but it
should be VK2/VK4. Shouldn't matter in practice though since
VK1/VK2/VK4/VK8/VK16 are all identicaly and just have different VTs.
