We don't consider it valid, but instead have special patterns to
detect the cases where we can figure out what the base register is.
Ah, I see. Like movqi+2. I'm seeing an unrecognized insn with such a
pattern coming from a large block of Ada code. I suspect that what's
happening is that combine is making it due to the setting of
REGNO_POINTER_FLAG and then somebody is changing it to use a different pseudo
without that flag. I'll have to look into it more closely.
