  [X86][CostModel] Add sext/zext from vXi1 tests to min-legal-vector-width.ll. NFC

We aren't properly costing extends from k-registers. I also added
command lines without avx512bw to be able to show all the different
extending strategies we have.

  Log Message:
  -----------
  [X86][CostModel] Improve costs for vXi1 sign_extend/zero_extend with avx512.

With avx512 vXi1 is legal and uses k-registers with many custom cases
for extending.

  Log Message:
  -----------
  [X86] Fix the cost of v16i1->v16i16 sext/zext on avx targets.

Previously we were hitting the scalarization case in the default
implementation.
