[Qemu-devel] [PULL 1/4] tcg-ppc64: Fix RLDCL opcode

[Richard Henderson <rth@twiddle.net>]

From: Anton Blanchard <anton@samba.org>

The rldcl instruction doesn't have an sh field, so the minor opcode
is shifted 1 bit. We were using the XO30 macro which shifted the
minor opcode 2 bits.

Remove XO30 and add MD30 and MDS30 macros which match the
Power ISA categories.
