system headers above the includes of generated '.inc' files that actually contain code. In a few targets this was already done pretty consistently, but it wasn't done *really* consistently anywhere. It is strictly cleaner IMO and necessary in a bunch of places where the DEBUG_TYPE is referenced from the generated code. Consistency with the necessary places trumps. Hopefully the build bots are OK with the movement of intrin.h... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206838 91177308-0d34-0410-b5e6-96231b3b80d8
