[NFC][InstCombine] Update sub-of-negatible.ll test 2019-12-04 15:49:36 +03:00
Roman Lebedev c780645736 [NFC][InstCombine] Some tests for sub-of-negatible pattern 
As we have previously estabilished, `sub` is an outcast,
and should be considered non-canonical iff it can be converted to `add`.

It can be converted to `add` if it's second operand can be negated.
So far we mostly only do that for constants and negation itself,
but we should be more through.
