On GLES >= 3.1 all the functionality that is currently relevant for

but it should be noted that these three tests expect that also points with a
centre outside the clip volume will be partially drawn when they overlap with
the clip volume because of being "wide" (i.e. when moving towards the clip
volume boundary a wide point would "naturally" move out). The OpenGL standard
defines that points should be clipped the moment the centre is outside the
clip volume (i.e. points will "pop" in and out of the view when moving across
the border). Hence, for a host implementation following the standard to the
letter these tests should actually fail.

Take into account the gallium uniform buffer indices when associating
host UBOs with gallium uniform buffers.
Previously the code disregarded the gallium uniform buffer indices,
leading, under specific circumstances, to the provision of incorrect
data to the shaders. The problem manifested typically when a context
contained active UBOs which were not accessed by a particular shader,
but ended up being used instead of the correct UBOs for that shader.
This occurred, for example, when running the dEQP-GLES3.functional.ubo.*
in batch mode, in which case left over UBOs from previous tests would
cause subsequent tests to fail.

Update the blit shader creation code to take the destination format
swizzle into account. This involves inverting the swizzle information
and using the inverted swizzle to reorder the texel components in the
shader. The new swizzle code also removes the need for having a special
case if the destination format uses emulated alpha.
This commit temporarily removes the VIRGL_FORMAT_R8G8B8X8_UNORM special
case. Improved support for it, and other similar "ignore alpha" cases,
is added back in an upcoming commit using appropriate swizzles.
At the moment we always recreate the shader in case we have a swizzle,
but a more efficient shader caching scheme could be devised to improve
this.
