[Mesa-dev] [PATCH 0/2] intel/compiler: Enable 8-bit constants

[Jose Maria Casanova Crespo]

New VK-GL-CTS tests that use VK_KHR_8bit_storage extension use
32-bit constants that are converted to 8-bit and there are stored in a
storage buffer.

Although 8-bit constants are not enabled by VK_KHR_8bit_storage
nir_opt_constant_folding already optimizes the 32 -> 8 integer
conversion to a 8-bit constant.

So we enable them in next two patches to not assert in this scenario.
