0e94f350ee glsl: push vertex count determination down one level 
We have the prog here, so we don't need the caller to work this out for
us.

567f1b2ee8 glsl: pass shader stage to lower_output_reads and handle tess control 
Tessellation control outputs can be read in directly without first
having been written. Accessing these will require some special logic
anyways, so just let them through.

V2: Never lower tess control output reads, whether patch or not -- both
can be read back by other threads.

2abbe941e1 glsl: add the tessellation extension to the list for the "layout" qualifier 
This is technically not needed, but it makes the compiler return a better
error message if tessellation is used with GLSL < 1.50.

Instead of:
    error: syntax error, unexpected NEW_IDENTIFIER, expecting $end
It returns:
    error: #version 150 layout qualifier `triangles' used

And the tessellation spec says:
    OpenGL 3.2 and GLSL 1.50 are required.
So it makes perfect sense.

There is no way to lower them, because the array sizes are unknown
at compile time.

5e3974338e gallium/radeon: remove buffer_unmap calls that can potentially decrease perf 
buffer_unmap is currently a no-op on radeon and done correctly on amdgpu.
I plan to fix it for radeon, but before that, all occurences of buffer_unmap
that can negatively affect performance in the future must be removed.

There are 2 reasons for removing buffer_unmap calls:
- There is a likelihood that buffer_map will be called again, so we don't
  want to unmap yet.
- The buffer is being released, which automatically unmaps it.
