Add DXIL operation for thread/group id operations. ID Name Description 93 ThreadId reads the thread ID 94 GroupId reads the group ID (SV_GroupID) 95 ThreadIdInGroup reads the thread ID within the group (SV_GroupThreadID) 96 FlattenedThreadIdInGroup provides a flattened index for a given thread within a given group (SV_GroupIndex) Also add llvm intrinsic which map to these intrinsics to DXIL operation.
