s390x: helper functions for system emulation

When running system emulation, we need to transverse through the MMU and
deliver interrupts according to the specification.

This patch implements those two pieces and in addition adjusts the CPU
initialization code to account for the new fields in CPUState....

s390x: Implement opcode helpers

There are some instructions that can't (or shouldn't) be expressed by pure
tcg code. For those, we call into externally compiled C functions.

This patch implements those C functions.

Remove unused function parameter from cpu_restore_state

The previous patch removed the need for parameter puc.
Is is now unused, so remove it.

S/390 CPU fake emulation

Because Qemu currently requires a TCG target to exist and there are quite some
useful helpers here to lay the groundwork for out KVM target, let's create a
stub TCG emulation target for S390X CPUs.

This is required to make tcg happy. The emulation target itself won't work...
