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.

@liushuyu Your previous revision seems more correct, some x86-64 targets do not enable sse2

granted, we don't run tests on most bare metal targets, but still

According to https://gitlab.com/x86-psABIs/x86-64-ABI, at least on Linux, "x86_64 (baseline)" means SSE + SSE2. I could not find information for Windows, but according to https://en.wikipedia.org/wiki/X86-64#AMD64 it seems like SSE registers are a standard at least for AMD64.

Oh, sorry, you meant freestanding implementations, my bad. I will change the test.

Done. The test is updated to gate both x86 platforms behind the sse2 feature gate.
