Need to add the abort, otherwise screwing up and invoking the body causes UB

at that point I'd prefer to use the Unreachable terminator in this PR or add the Abort terminator in a separate PR (I'm inclined to use the Unreachable terminator since that should still often result in crashes and adding a new terminator seems like a lot of stuff for just the intrinsics, unless there are other use cases for it)

[oli-obk]

I removed the Abort terminator change
