tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long.

These changes are needed for build environments where
sizeof(long) != sizeof(void *), especially for w64.

See 4b4a72e5 which fixed the
same issue for the other targets.

The disas_a5() function provided a TCG tmp variable which was populated
by the respective opcode implementations, but freed at the end of the
function in generic code.

That makes it really hard for code review, so let's move the freeing
to the same scope as the actual allocation.

tmp2 = tcg_temp_new_i64() is already executed unconditionally,
so there is no need to call it a second time for 64 bit hosts.

tcg_gen_shl_i64 needs a 3rd argument of type TCGv_i64.
Set tmp4 so it can be used here.

v2:
Don't call tcg_const_i64() inside of the loop
because it creates additional code.

This is the main meat part of the patch set. It implements emulation for an
s390x CPU.

The code does all the optimizations that are common for TCG code:

 - direct branches
 - cc optimization
 - unrolling of simple microcode loops

I'm still open for suggestions on speedups of course :).

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.

Function gen_pc_load was introduced in commit
d2856f1a.
The only reason for parameter searched_pc was
a debug statement in target-i386/translate.c.

Parameter puc was needed by target-sparc until
commit d7da2a10.

Remove searched_pc from the debug statement and remove both
parameters from the parameter list of gen_pc_load.

As the function name gen_pc_load was also misleading,
it is now called restore_state_to_opc. This new name
was suggested by Peter Maydell, thanks.

v2: Remove last parameter, too, and rename the function.

v3: Fix [] typo in target-arm/translate.c.
    Fix wrong SHA1 object name in commit message (copy+paste error).

We need to add some more logic to the CPU description to leverage emulation
of an s390x CPU. This patch adds all the required helpers, fields in CPUState
and constant definitions required for user and system 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
though.
