```- create a clang built-in in Builtins.td - link dot4add_u8packed in hlsl_intrinsics.h - add lowering to spirv backend through expansion of operation as OpUDot is missing up to SPIRV 1.6 in SPIRVInstructionSelector.cpp - add lowering to spirv backend using OpUDot if applicable SPIRV version or SPV_KHR_integer_dot_product is enabled - add dot4add_u8packed intrinsic to IntrinsicsDirectX.td and mapping to DXIL.td op Dot4AddU8Packed - add tests for HLSL intrinsic lowering to dx/spv intrinsic in dot4add_u8packed.hlsl - add tests for sema checks in dot4add_u8packed-errors.hlsl - add test of spir-v lowering in SPIRV/dot4add_u8packed.ll - add test to dxil lowering in DirectX/dot4add_u8packed.ll ``` Resolves #99219
