code that includes Intrinsics.gen directly. This never showed up in my testing because the old Intrinsics.gen was still kicking around in the make build system and was correct there. =[ Thankfully, some of the bots to clean rebuilds and that caught this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171373 91177308-0d34-0410-b5e6-96231b3b80d8
