[Qemu-ppc] [PULL 082/130] target-ppc: Add Flag for bctar

[Alexander Graf]

From: Tom Musta <address@hidden>

This patch adds a flag for the bctar instruction.  This instruction
is being introduced via Power ISA 2.07.

Also, the flag is added to the Power8 machine model since the P8
processor supports this instruction.
