Put in infrastructure for tessellation, geometry, and compute stages, and partially flesh out with built-in functions.

Added the built-in functions EmitVertex(), EndPrimitive(), barrier(), memoryBarrier(), memoryBarrierAtomicCounter(), memoryBarrierBuffer(), memoryBarrierImage(), memoryBarrierShared(), and groupMemoryBarrier().

Have not added any new built-in variables.

Also changed the linear performance relateToOperator() to a high-performance version.
