FTR, this has broken general register printing for ARM/AArch64. Now
"info reg" shows nothing.
Given there are already remote stubs, probes and gdbservers running out
there, this is an undesirable change to have.
I had an IRC chat with Christian and he pointed me at some documentation
stating empty-group registers should not be printed, but i think this is
a case where the implementation has diverged from the documentation.

We could probably patch up any non-standard target description XML's
from now on, but the existing behavior may have to be preserved.
Most targets under features/ do not specify group="general" in their
XML files for anything (only S/390 does); it seems like that should
maybe be fixed either way?
