  [InstCombine] simplify code for matching shift-logic-shift pattern; NFC

We can match and capture in one statement. Also, make the
code more closely resemble the description comment by using
the constant name of an operand value.

  Log Message:
  -----------
  [InstCombine] add tests for diff-of-squares; NFC

Ideally, these negative tests would have been added
before 68c197f07eea to make sure the specific
operand matching is working as expected, but I did
not remember to include them.
