Detailed Description

MatchContext can repurpose existing patterns to behave differently under a certain context.

For instance, m_Opc(ISD::ADD) matches plain ADD nodes in normal circumstances, but matches VP_ADD nodes under a custom VPMatchContext. This design is meant to facilitate code / pattern reusing.
