tests: Fix the SIMD FFI tests with certain x86 configuration

This pull request fixes the SIMD FFI tests with certain x86 configurations by gating the SSE2 intrinsic behind the `sse2` feature gate. A generic LLVM intrinsic that is easy to un-fuse on those platforms is added to compensate for those platforms.
