[PULL 29/33] target: Use CPUArchState as interface to target-specific CPU state

["Philippe Mathieu-Daudé" <philippe.mathieu.daude@gmail.com>]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

While CPUState is our interface with generic code, CPUArchState is
our interface with target-specific code. Use CPUArchState as an
abstract type, defined by each target.
