[PATCH] D51842: [X86ISel] Implement byval lowering for Win64 calling convention

[Eli Friedman via Phabricator via llvm-commits]

If you're a frontend author, I would suggest not using byval, ever; it mostly exists for compatibility with existing C calling conventions.  (Of course, it should still work if the frontend requests it.)
