  s390x: Fix stoc direction

The store conditional instruction wants to store when the condition
is fulfilled, so we should branch out when it's not true.

The code today branches out when the condition is true, clearly
reversing the logic. Fix it up by negating the condition.

  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.

  s390x: Add interlocked access facility 1 instructions

We're currently missing all instructions defined by the "interlocked-access
facility 1" which is part of zEC12. This patch implements all of them except
for LPD and LPDG.

Patch queue for s390 - 2015-05-13

A few TCG fixes for the s390x target. Nothing special, but with these
applied I can run most of the SLE12 binaries in Linux-user emulation.
