Summary:
While the specification says that the 64bit registers are prefixed with
`x`, it seems that many people still use `r`. Until recently, we had been using
the `r` prefix instead of the `x` prefix in ds2. This caused lldb to fail during
unwinding. I think it's reasonable to check for a register prefixed with `r`,
since some people still choose to use `r`.
