target-s390: Convert LRA

Note that truncating the store to r1 based on PSW_MASK_64
is incorrect. We always modify the entire register.

target-s390: Convert INSERT CHARACTERS UNDER MASK

Change the CC handling to be more like TEST UNDER MASK, with val & mask.
This lets us handle ICMH much more like ICM.

target-s390: Convert ADD LOGICAL CARRY and SUBTRACT LOGICAL BORROW

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...

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
values need returning (e.g. quotient+remainder) as well.

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

Which highlights a lot of cc helpers that no longer exist.

target-s390x: rename helper flags

Rename helper flags to the new ones. This is purely a mechanical change,
it's possible to use better flags by looking at the helpers.
