[XRay] [compiler-rt] Stub out architectures we don't do arg1 logging on.

[pelikan]

Summary

rL297000 forgot to include code for three architectures that appeared
since I wrote the first version. This gives them the same treatment as ARMs
have for now - write stubs and wait for someone to actually implement it.
