Alexander Graf 13f67dd582 s390x: Add some documentation in opcode list 
I find it really hard to grasp what each field in the opcode list means.
Slowly walking through its semantics myself, I figured I'd write a small
summary at the top of the file to make life easier for me and whoever
looks at the file next.

Richard Henderson 8612c93583 target-s390: Implement SAM specification exception 
Also, these are user-mode instructions; allow their use
in CONFIG_USER_ONLY.

Alexander Graf 44dd33ba8f s390x: Implement SAM{24,31,64} 
The SAM instructions simply change 2 bits in PSW.MASK to advertise
the current memory mode. While we can't fully guarantee that 31 bit
mode (or even remotely 24 bit mode) actually work correctly, we don't
check whether lpswe modifies these bits, so we shouldn't keep the
guest from executing SAM instructions either.

This patch implements all SAM instrutions with their actual PSW changing
semantics, making more recent Linux kernels boot properly which do issue
a SAM31 call during early boot.
