5799a730 - [SYCL] Disable clang optimization for __imf_vaddsu2 libdevice function (#21776)

[SYCL] Disable clang optimization for __imf_vaddsu2 libdevice function (#21776) We observed pre-ci failures for SYCL e2e test for __imf_vaddsu2 function. It turned out to be a compiler optimization problem introduced by latest llvm pulldown. This PR disables clang optimization for __imf_vaddsu2 to unblock pre-ci as a quick workaround. We also removed previous workaround to bypass another compiler issue leading to llvm-spirv crash. --------- Signed-off-by: jinge90 <ge.jin@intel.com>
