  [InstCombine][InstSimplify] add tests for i1/i2 mul with no-wrap; NFC

A bug was introduced with 68c197f07eeae71 as noted in the
post-commit review comments, and there are potentially
missed smaller transforms/simplifications because no-wrap
multiply with only 1 or 2 bits eliminates some potential
results.
