Consider the following pattern:

  %binop_ = binop %x, %y
  %select_ = select %c, %binop_, %x

If there is an identity `%identity` operand for `binop`, it is possible to transform
the above code to:

  %opearand = select %c, %y, %identity
  %result = binop %x, %operand

This transformation is profitable when `%identity` is all zeroes or
ones.

This patch commits a test for such patterns.
