Richard Henderson 14db18997e target/ppc: Remove POWERPC_EXCP_STCX 
Always use the gen_conditional_store implementation that uses
atomic_cmpxchg.  Make sure and clear reserve_addr across most
interrupts crossing the cpu_loop.

Laurent Vivier cd71c08964 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.
