Move definitions that were 100% identical except for the name into a
list of aliases so that we don't register duplicate CPU types.
Drop the accompanying comments since they don't really add value.
We need to support recursive lookup due to code names referencing a
generic name referencing a specific model revision.
List aliases separately for -cpu ?.

Unlike derived PVR constants mapped to CPU_POWERPC_G2LEgp3, the
"G2leGP3" model definition itself used the CPU_POWERPC_G2LEgp1 PVR.
Fixing this will allow to alias CPU_POWERPC_G2LEgp3-using types to
"G2leGP3".

It was defined to ..._MPC8545E_v21 rather than ..._MPC8547E_v21.
Due to both resolving to CPU_POWERPC_e500v2_v21 this did not show.
Fixing this nontheless helps with QOM'ifying CPU aliases.

are useful for generic "start/end of TB" code, used for more than just
icount. Rename them to gen_tb_start/end.

Introduce ENV_OFFSET macros which can be used in non-target-specific

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions.
The field may not be called "env" due to it being poisoned.

The bit that makes a dcbz instruction a dcbzl instruction was declared as
reserved in ppc32 ISAs. However, hardware simply ignores the bit, making
code valid if it simply invokes dcbzl instead of dcbz even on 750 and G4.
Thus, mark the bit as unreserved so that we properly emulate a simple dcbz
in case we're running on non-G5s.
While at it, also refactor the code to check the 970 special case during
runtime. This way we don't need to differenciate between a 970 dcbz and
any other dcbz anymore. We also allow for future improvements to add e500mc
dcbz handling.
