Roman Lebedev 6b1e66b188 [InstCombine][NFC] Add tests for variable mask canonicalization in masked merge 
Summary:
Masked merge has a pattern of: `((x ^ y) & M) ^ y`.
But, there is no difference between `((x ^ y) & M) ^ y` and `((x ^ y) & ~M) ^ x`,
We should canonicalize the pattern to non-inverted mask.
