[Qemu-devel] [PULL 08/24] disas: Remove uses of CPU env

[Markus Armbruster <armbru@redhat.com>]

From: Peter Crosthwaite <crosthwaitepeter@gmail.com>

disas does not need to access the CPU env for any reason. Change the
APIs to accept CPU pointers instead. Small change pattern needs to be
applied to all target translate.c. This brings us closer to making
disas.o a common-obj and less architecture specific in general.
