Summary: As discussed on llvm-dev[1]. This change adds the basic boilerplate code around having this intrinsic in LLVM: - Changes in Intrinsics.td, and the IR Verifier - A lowering pass to lower @llvm.experimental.guard to normal control flow - Inliner support [1]: http://lists.llvm.org/pipermail/llvm-dev/2016-February/095523.html Reviewers: reames, atrick, chandlerc, rnk, JosephTremoulet, echristo Subscribers: mcrosier, llvm-commits Differential Revision: http://reviews.llvm.org/D18527 llvm-svn: 264976
