* Smashed about 20 commits into the New TCG Target patch,
which is fully functional from the beginning.

Before gcc 4.2, __builtin___clear_cache doesn't exist, and

Some hosts (amd64, ia64) have an ABI that ignores the high bits
of the 64-bit register when passing 32-bit arguments. Others,
like s390x, require the value to be properly sign-extended for
the type. I.e. int32_t must be sign-extended and uint32_t
must be zero-extended to 64-bits.
To effect
Verify that we have all the instruction extensions that we generate.
Future patches can tailor code generation to the set of instructions
that are present.

We already have stubs for a TCG target on S390, but were missing code that
would actually generate instructions.
So I took Uli's patch, cleaned it up and present it to you again :-).
I hope I found all odd coding style and unprettiness issues, but if you
still spot one feel free to nag about it.

The TCG translator will *not* work in 32-bit mode, and there is a
check added to query_facilities to enforce that.
However, QEMU can run in KVM mode when built in 32-bit mode, and
this patch is just good enough to enable that method to continue.
