[PATCH] D141891: [VP][DAGCombiner] Introduce gneralized pattern match for vp sdnodes.

[Yeting Kuo via Phabricator via llvm-commits]

fakepaper56 added a comment.

@simoll There is some difference between my implement and yours:

1. Operand with true mask does not fail in `match()` of `VPMatchContext`.
2. Operand with normal opcode does not fail in `match()` of `VPMatchContext` if its opcode is same as the input opcode.
3. Make `VPMatchContext` be only constructed by vp root nodes. It could help for point 2.
4. I removed the member function `getFunctionOpCode` and  `isCompatible`.

Do you have any idea for my change?
