303c681a8f target/s390x: Implement EXECUTE via new TranslationBlock 
Previously, helper_ex would construct the insn and then implement
the insn via direct calls other helpers.  This was sufficient to
boot Linux but that is all.

It is easy enough to go the whole nine yards by stashing state for
EXECUTE within the cpu, and then rely on a new TB to be created
that properly and completely interprets the insn.

a72da8b7f5 target/s390x: Fix EXECUTE with R1==0 
The PoO specifies that when R1==0, no ORing into the insn
loaded from storage takes place.  Load a zero for this case.

8350079329 target/s390x: Fix some helper_ex problems 
(1) The OR of the low bits or R1 into INSN were not being done
consistently; it was forgotten along all but the SVC path.
(2) The setting of ILEN was wrong on SVC path for EXRL.
(3) The data load for ICM read too much.

Fix these by consolidating data load at the beginning, using
get_ilen to control the number of bytes loaded, and ORing in
the byte from R1.  Use extract64 from the full aligned insn
to extract arguments.

Pass in ILEN rather than RET as the more natural way to give
the required data along the SVC path.

Modify ENV->CC_OP directly rather than include it in the
functional interface.
