[PATCH] D46179: [X86] Lowering adds/addus/subs/subus intrinsics to native IR (LLVM part)

[Craig Topper via Phabricator via llvm-commits]

I'm also concerned that the more complex patterns are easier for other optimizations to simplify a little and break. The simpler things like pmin/pmax or pabs aren't so bad to not match when they get optimized a little.
