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
though.

Our cpu keeps multiple seperate address spaces open at the same time
(similar to x86 with a bunch of cr0s), defined by address space control
elements in various control registers. Linux uses primary, secondary and
home space to address user space and kernel space. The third one is user

psw.mask is rougly the same as RFLAGS, cr0 and cr4 on x86_64 combined. So IMHO
it looked like a pretty

The translation block (TB) refers to a block of host instructions,
translated from some block of target instructions under some
assumptions. The assumptions used when translating (for example, user
vs supervisor mode in the CPU state) are recorded to TB flags. If the
