David Hildenbrand recently posted a series of patches correcting
various mistakes in the computation of ILEN for various instructions
in the respective helpers.
I think a better approach is to include ilen in the set of unwind
data for each insn. In this way we can fix these sorts of errors
automatically. At the same time begin to wean ourselves away from
ILEN_AUTO, which requires re-reading from the instruction stream.
Almost certainly 2.11 material. Thoughts?

Richard Henderson (4):
target/s390x: Add ilen to unwind data
target/s390x: Use ILEN_UNWIND in trivial cases
target/s390x: Use unwind info in STSI
target/s390x: Use ilen from unwind in tlb_fill
