target-ppc: Split model definitions out of translate_init.c

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....

Save memory allocation in the elf loader

The current elf loader uses too much memory. For example, I have a
executable with a bss section of 400 MB and I set the ram size to 512
MB. Qemu uses about 780MB of RAM (which is fine), but there's a peak at
1.6 GB during initialization (this is not fine)....

target-ppc: Add mechanism for synchronizing SPRs with KVM

Currently when runing under KVM on ppc, we synchronize a certain number of
vital SPRs to KVM through the SET_SREGS call. This leaves out quite a lot
of important SPRs which are maintained in KVM. It would be helpful to...

target-ppc: Synchronize FPU state with KVM

Currently qemu does not get and put the state of the floating point and
vector registers to KVM. This is obviously a problem for savevm, as well
as possibly being problematic for debugging of FP-using guests.

This patch fixes this by using new extensions to the ONE_REG interface to...

target-ppc: Convert CPU definitions

Turn the array of model definitions into a set of self-registering QOM
types with their own class_init. Unique identifiers are obtained from
the combination of PVR, SVR and family identifiers; this requires all
alias #defines to be removed from the list. Possibly there are some more...

target-ppc: Introduce abstract CPU family types

Instead of assigning *_<family> constants, set .parent to a family type.

Introduce a POWERPC_FAMILY() macro to keep type registration close to
its implementation. This macro will need tweaking later.

Don't attempt to suppress registration of CPU types, since the criteria

Since we can't check a field set in a class_init function before
registering the type that leads to execution of that function, guard the...
