Philippe Mathieu-Daudé b74c898158 user: Move 'linux-user/cpu_loop-common.h' -> 'user/cpu_loop.h' 
"linux-user/cpu_loop-common.h" is generic enough to be used by
bsd-user, so rename it as "user/cpu_loop.h".

Mechanical change running:

  $ sed -i -e 's,cpu_loop-common.h,user/cpu_loop.h,' \
                $(git grep -l cpu_loop-common.h)

This struct is unused since Peter's
Commit b8ae597f0e ("linux-user/sparc: Fix errors in target_ucontext
structures")

However, hmm, I'm a bit confused since that commit modifies the
structure and then removes it, was that intentional?
