[PULL 12/31] cpu: Split as cpu-common / cpu-sysemu

[Richard Henderson <richard.henderson@linaro.org>]

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

The current cpu.c contains sysemu-specific methods.
To avoid building them in user-mode builds, split the
current cpu.c as cpu-common.c / cpu-sysemu.c.

Start by moving cpu_get_crash_info().
