[PATCH] D71739: [AssumeBundles] Use operand bundles to encode alignment assumptions

[John McCall via Phabricator via cfe-commits]

Hmm.  It does seem to be true that operand bundles don't inherently enforce that the names are unique on a callsite; the verifier just has an ever-growing list of bundles that it does that for specially.  That feels weird to me, but alright.
