Use the new float*_muladd interface to softfloat.

Note that we were failing to set the rounding mode in fpu_status.

target-s390: Convert STCM
target-s390: Convert FP ADD, COMPARE, LOAD TEST/ROUND/LENGTHENED
target-s390: Convert LRA
Note that truncating the store to r1 based on PSW_MASK_64is 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 bothhelpers 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 DIVIDE
target-s390: Convert 64-bit MULTIPLY LOGICAL
Use a new "retxl" member of CPUS290XState to return the "eXtra Low" partof a 128-bit value. That said, this will get used when two independentvalues need returning (e.g. quotient+remainder) as well.
At the same time, shuffle the elements of CPUS390XState to get this new...
target-s390: Register helpers
Which highlights a lot of cc helpers that no longer exist.
exec: move include files to include/exec/

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.

target-s390x: switch to AREG0 free mode
Add an explicit CPUState parameter instead of relying on AREG0.
Remove temporary wrappers and switch to AREG0 free mode.

target-s390x: avoid AREG0 for condition code helpers
Make condition code helpers take a parameter for CPUState insteadof relying on global env.
Move helpers.h to helper.h
Provides a file naming scheme consistent with other targets.
