Wrap integer textures with correct wrap mode in HLSL The wrap mode information for all three dimensions is packed to a single integer in order to conserve sampler metadata space. Only one int4 vector is used for the metadata for a single sampler. The sampler metadata is now packed into a struct instead of an array of integers in order to make the code more readable and maintainable. The internalFormatBits field is not removed in this patch. It's better to remove it in a separate patch, so restoring it is easier in case it will be used for optimizing some of the texture sampling functions. The wrap mode passed in sampler metadata is used to wrap the texture coordinates in the code generated to implement ESSL 3.00 integer texture sampling built-ins. Those dEQP-GLES3.functional.texture.units.* tests that sample from integer cube maps still fail on Intel D3D after this change, presumably due to driver issues.
