Summary: Add function to AutoUpgrade to change the datalayout of old X86 datalayout strings. This adds "-p270:32:32-p271:32:32-p272:64:64" to X86 datalayouts that are otherwise valid and don't already contain it. This also removes the compatibility changes in https://reviews.llvm.org/D66843. Datalayout change in https://reviews.llvm.org/D64931. Reviewers: rnk, echristo Subscribers: hiraditya, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D67631 llvm-svn: 372267
