We will need a target-specific hook for adjusting registers
in the parent during clone. Add an empty inline function for
each target, and invoke it from the proper places.

We will need a target-specific hook for adjusting registers
in the parent during clone. To avoid confusion, rename the
one we have to make it clear it affects the child.
At the same time, pass in the flags from the clone syscall.
We will need them for correct behaviour for Sparc.

These headers all use TARGET_CPU_H as header guard symbol. Reuse of
the same guard symbol in multiple headers is okay as long as they
cannot be included together.
Since we can avoid guard symbol reuse easily, do so: use guard symbol
$target_TARGET_CPU_H for linux-user/$target/target_cpu.h.

The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU
related -- they are specific to the TLS ABI for a a particular OS.
Move them into the linux-user/ tree where they belong.
target-lm32 had entirely unused implementations, since it has no
linux-user target; just drop them.
