Summary: This makes it so that IR files using triples without an environment work out of the box, without normalizing them. Typically, the MSVC behavior is more desirable. For example, it tends to enable things like constant merging, use of associative comdats, etc. Addresses PR42491 Reviewers: compnerd Subscribers: hiraditya, dexonsmith, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D64109 llvm-svn: 365387
