[PATCH] D45664: [InstCombine] Canonicalize variable mask in masked merge

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri updated this revision to Diff 142557.
lebedev.ri added a comment.

Slightly cleanup the matcher by using `m_CombineAnd()`,
which allows to use `m_c_And()` when looking for `A` part.

I'm not sure whether it actually matter because i was not able
to come up with a testcase, but it looks a bit cleaner anyway..
