This patch doesn't touch NTID since it seems very difficult (or
impossible) to generate. Seemingly because the state tracker or glsl
compiler is turning gl_WorkGroupSize into a immediate. Such a
transformation is not possible with GL_ARB_compute_variable_group_size
but gl_WorkGroupSize is not avail
somehow it doesn't really look like that it is worth the effort as the
generated shaders are worse in avg?

Are they? Fewer special reg loads = better...

okay right, if loading those special regs is indeed more expensive
than doing the read + a few extbf then I see the point of this
optimization

anyway, I think it might make sense to take a look at the shaders hurt
most as I suspect there might be a way to improve the situation a
little

I don't really see how things like RDSV(COMBINED_TID) + EXTBF + EXTBF
can be improved unless you create separate RDSV instructions (which is
against the point of this patch) or merge the EXTBF with later
instructions (and I don't really see how that can be done).
It's only increases the size of gl
