[PATCH] D75357: [X86] Add a private member function determinePaddingPrefix for X86AsmBackend

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Do you have a plan how `determinePaddingPrefix` will be used? Without a plan, there may be some churn that moves things around. The plan should also include how the complex logic will be tested eventually.
