ES3.1: Set unordered access view related resource limits on D3D11
This patch sets the implementation-dependent resources limits related
to unordered access views (images, shader storage blocks, atomic
counter buffers and fragment shader outputs) on D3D11 back-ends.
For pixel shaders, the render targets and unordered access views share
the same resource slots when being written out, so we plan to allocate
these slots as follows:
- As there are 8 slots for UAVs and RTVs in feature level 11_0, currently
we assign 1 slot for atomic counter buffer and 7 slots that are shared
among images, shader storage blocks and fragment shader outputs.
- As there are 64 slots for UAVs and RTVs in feature level 11_1, currently
we assign 4 slots for atomic counter buffers and 60 slots that are
shared among images, shader storage blocks and fragment shader
outputs.
We also limit the maximum number of draw buffers to 7 if we create ES 3.1
context on D3D11 feature level is 11_0 because the value of combined shader
output resources is 7.
This patch also labels several dEQP cases from "FAIL" to "SKIP" because
since the resource limits on ssbos, atomic counter buffers and images
in rendering pipeline are set in D3D11 back-ends, the GLSL programs in
these cases can pass all the related link checks, thus these cases will
crash due to reaching the unimplemented parts when they are running on
ANGLE D3D11 back-ends.
