Hi David,

No RISC architecture can store directly to MEM, so the expected RTL in
g++.dg/init/vbase1.C is wrong. I am adding XFAIL for PowerPC. This
probably should be disabled for ARM and other RISC architectures.
I observed the same problem in arm.
This passes for aarch64 and mips as they have zero register to do that.
However, other RISC might not have that feature, for example arm and
RS6000 in this case.

Dollar sign is not a valid identifier on AIX, so g++.dg/cpp/ucn-1.C
will produce an additional error on AIX.
* g++.dg/init/vbase1.C: XFAIL powerpc*-*-*.
* g++.dg/cpp/ucn-1.C: Expect error for dollar sign identifier on AIX.
Thanks, David
