Fix PR12312
- Add a target-specific DAG optimization to recognize a pattern PTEST-able.
Such a pattern is a OR'd tree with X86ISD::OR as the root node. When
X86ISD::OR node has only its flag result being used as a boolean value and
all its leaves are extracted from the same vector, it could be folded into an
X86ISD::PTEST node.
