linux-user: create a dummy per arch cpu_loop.c
Create a cpu_loop-common.h for future use by
these new files and use it in the existing
main.c
Introduce target_cpu_copy_regs():
declare the function in cpu_loop-common.h
and an empty function for each target,
to move all the cpu_loop prologues to this function.
