Bug ID: 105464
Summary: Reading per-patch outputs in Tessellation Control
Shader returns undefined values

Patch for tessellation demo to reproduce the issue
As mentioned in the title, reading a per-patch output variable that was written
by a different invocation produces undefined results even after a barrier()
The attached patch changes the tessellation control shader of the
'tessellation' demo from Sascha Willems' Vulkan samples in that it reads the
tessellation levels from a per-patch output array. Note that the shader needs
to be recompiled manually in order to reproduce the issue.
