Target s390x uses ad-hoc macro magic to guess if the compiler
supports the GCC extension __uint128_t. This patch uses the
the dedicated macro CONFIG_INT128 defined by configure instead.
This fixes compilation with the CIL source code analyzer, which
uses GCC as a preprocessor but does not support __uint128_t.

I'm resonably certain that the carry/borrow-out condition for both
helpers was incorrect, failing to take into account the carry-in.
Adding the new CC_OP codes also allows removing the awkward interface
we used for the slb helpers.

Use a new "retxl" member of CPUS290XState to return the "eXtra Low" part
of a 128-bit value. That said, this will get used when two independent
values need returning (e.g. quotient+remainder) as well.
At the same time, shuffle the elements of CPUS390XState to get this new
space from existing padding in the structure.

Make integer helpers take a parameter for CPUState instead
of relying on global env.
