Silly question - why is this enum ordered so differently to llvm/include/llvm/Support/CodeGen.h?

I've checked and the order doesn't appear to matter apart from some sanitizer tests which have the frame pointer metadata written like: !1 = !{i32 7, !"frame-pointer", i32 2}. I can make it consistent if you'd like.

I've no strong objection to keeping it as it is but it would make sense to match the llvm implementation (assuming that's the one hardwired by metadata) - but I assume that can be done as a followup PR. Thanks for checking
