Most targets were using offsetof(CPUFooState, breakpoints) to determine
how much of CPUFooState to clear on reset. Use the next field after
CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise.

Or, partially. The fundamental primitives for the port are gen_load_mem
and gen_store_mem, which take a callback to emit the memory operation.
For that, we continue to use the original inline functions that forward
to the new ops, rather than replicate the same thing privately.
That said, all free-standing calls to tcg_gen_qemu_* have been converted.
The 32-bit floating-point references now use _i32 opcodes, eliminating
a truncate or extension.

This allows significantly more threading, and occasionally larger TBs,

With appropriate flushing when the PALBR changes, the target of
a CALL_PAL is so predictable we can chain to it.

The destination of the call_pal, and the cpu state, is very predictable;
there's no need for exiting the cpu loop.

Basing the alarm off the rtc_clock was silly. It leads to horrible
spinning in the guest after being suspended and resumed, as it tries
to catch up with lost ticks.
This requires adding an accessor for reading the vm_clock too.

Both fields are used in VMState, thus need to be moved together.

The gen_icount_start/end functions are now somewhat misnamed since they
are useful for generic "start/end of TB" code, used for more than just
icount. Rename them to gen_tb_start/end.

Note that target-alpha accesses this field from TCG, now using a
negative offset. Therefore the field is placed last in CPUState.
