        <pre>With the landing of update f75a5cccd800bb011b44c799415efdfe547d6076 at OpenGL
CTS 4.6.0 
KHR-GL46.tessellation_shader.single.xfb_captures_data_from_correct_stage starts
failing.

commit f75a5cccd800bb011b44c799415efdfe547d6076
Author: Piers Daniell <<a href="mailto:pdaniell@nvidia.com">pdaniell@nvidia.com</a>>

    Use non-arrayed varying name for TCS blocks

    This is a partial revert of CL 2625 to restore naming the
    value member of the BLOCK_INOUT interface block as
    "BLOCK_INOUT.value" rather than "BLOCK_INOUT[0].value".

    Affects:

    KHR-GL46.tessellation_shader.single.xfb_captures_data_from_correct_stage

    Components: OpenGL

    VK-GL-CTS issue: 1388

    Change-Id: I9ef6453ec5465a0fa5561220cc9d7bfe54298416

Mesa populates the transform feedback candidates with the following names
because TCS interface block is arrayed:

BLOCK_INOUT[0].value
BLOCK_INOUT[1].value
BLOCK_INOUT[2].value
BLOCK_INOUT[3].value

As now the tests has been changed to use as XFB name BLOCK_INOUT.value the
variable isn't found and a linking error is raised.

More details about the motivations of the test modification are available at
Khronos Gitlab.</pre>
