freedreno/ir3: Add workaround for VS samgq
This instruction needs a workaround when used from vertex shaders.
Fixes:
dEQP-GLES3.functional.shaders.texture_functions.texturegradoffset.sampler2dshadow_vertex
dEQP-GLES3.functional.shaders.texture_functions.texturegradoffset.sampler3d_fixed_vertex
dEQP-GLES3.functional.shaders.texture_functions.texturegradoffset.sampler3d_float_vertex
dEQP-GLES3.functional.shaders.texture_functions.textureprojgradoffset.sampler2dshadow_vertex
dEQP-GLES3.functional.shaders.texture_functions.textureprojgradoffset.sampler3d_fixed_vertex
dEQP-GLES3.functional.shaders.texture_functions.textureprojgradoffset.sampler3d_float_vertex
dEQP-GLES3.functional.shaders.texture_functions.textureprojgrad.sampler2dshadow_vertex
