On Intel hardware when a geometry shader outputs GL_POINTS primitives we
only need to emit vertex control bits if it emits vertices to non-zero
streams, so use a flag to track this.
This flag will be set to TRUE when a geometry shader calls EmitStreamVertex()
or EndStreamPrimitive() with a non-zero stream parameter in a later patch.

For things that are not visible to the GL API, we've been trying to
transition away from GL types. Unless Brian or Chris object, I think
I'd rather have this be bool (and true / false below).
Sounds fine.
