  Log Message:
  -----------
  [LV][NFC] Remove remaining uses of undef in tests (#169357)

Split off from PR #163525, this standalone patch replaces almost all the
remaining cases where undef is used as value in loop vectoriser tests.
This will reduce the likelihood of contributors hitting the `undef
deprecator` warning in github.
NOTE: The remaining use of undef in iv_outside_user.ll will be fixed in
a separate PR.

I've removed the test stride_undef from version-mem-access.ll, since
there is already a stride_poison test.
