tbh I'm not entirely sure why we're here at all for an x86_64 target? this
method is only be called when the target cpu is llvm::Triple::aarch64. It
fetches the value of the x16 register just before this, and returns if no such
register is found I think? But yes, I would change these to not get the ABI
and instead call Process::FixCodeAddress instead of getting the ABI at all, and
asserting if we could not. Process::FixCodeAddress will silently return the
same value if there is no ABI (and if it gets an ABI without a FixCodeAddress
override method, it will also return the same value).
