s390x: use CONFIG_INT128 to detect __uint128_t

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...

Adding the new CC_OP codes also allows removing the awkward interface...

target-s390: Convert 64-bit MULTIPLY LOGICAL

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

At the same time, shuffle the elements of CPUS390XState to get this new...
