fix #109
Now we only have the implements of intrinsics SIMD on x86_64 and aarch64. We could just enable the std SIMD on other platforms. Since we have
__has_include(<experimental/simd>)
, so that it's not a big deal if the target platform even doesn't have the std platform and just fall back to non-SIMD. And we could believe in that once the c++ standard library supports a new platform, we could get benefits in it immediately.Tested on Arch Linux x86_64 and Arch LInux RISC-V
