9761ad7571 PPC: Introduce an alias cache for faster lookups
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

9baea4a303 target-ppc: Remove vestigial PowerPC 620 support
The PowerPC 620 was the very first 64-bit PowerPC implementation, but
hardly anyone ever actually used the chips.  qemu notionally supports the
620, but since we don't actually have code to implement the segment table,
the support is broken (quite likely in other ways too).

This patch, therefore, removes all remaining pieces of 620 support, to
stop it cluttering up the platforms we actually care about.  This includes
removing support for the ASR register, used only on segment table based
machines.

e9a9607527 target-ppc: Move CPU aliases out of translate_init.c
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.

953af181f5 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.
