[PATCH] D26718: [llvm] Iterate SmallPtrSet in reverse order to uncover non-determinism in codegen

[Mandeep Singh Grang via llvm-commits]

mgrang added a comment.

Based on discussions on the associated email thread:

I have based this patch on LLVM_ENABLE_ABI_BREAKING_CHECKS. I have also turned it ON by default so that this is enabled in buildbot by default.
The user can toggle the behavior with the -mllvm -reverse-iterate flag.
