This patch adds CPU PVR definition for POWER8,
and enables QEMU to launch guests on POWER8 hardware.

MPC86xx processors are based on the e600 core, which is not the case
in qemu where it is based on the 7400 processor.
This patch creates the e600 core and instantiates the MPC86xx
processors based on it. Therefore, adding the high BATs, the SPRG
4..7 registers, which are e600-specific [1], and a HW MMU model (as 7400).
This allows to define the MPC8610 processor too.
Tested with a kernel using the HW TLB misses.

When running QEMU with "-cpu ?" we walk through every alias for every
target CPU we know about. This takes several seconds on my very fast
host system.
Let's introduce a class object cache in the alias table. Using that we
don't have to go through the tedious work of finding our target class.
Instead, we can just go directly from the alias name to the target class
pointer.
This patch brings -cpu "?" to reasonable times again.
Before:
real 0m4.716s
After:
real 0m0.025s

Move array of CPU aliases to cpu-models.c, alongside model definitions.
This requires to zero-terminate the aliases array since ARRAY_SIZE() can
no longer be used in translate_init.c then.

Now that model definitions only reference their parent type, model
definitions are independent of the family definitions and can be
compiled independently of TCG translation.
Keep all #if defined(TODO) code local to cpu-models.c.
