Thanks for the feedback. I've updated the fix to address this concern. The
SSE4.1 enablement is now scoped specifically to Windows MSVC targets using
getTriple().isWindowsMSVCEnvironment(), which ensures it doesn't affect Linux
x86_64 targets. The updated commit has been force-pushed to the branch.
