We have already computed the rotated value of the imm8
portion of the complete imm12 encoding. No sense leaving
the combination of rot + rotation to the caller.
Create an encode_imm12_nofail helper that performs an assert.
This removes the final use of the local "rotl" function,
which duplicated our generic "rol32" function.

Currently we define a lot of jobs for our custom runners:
for both aarch64 and s390x we have
- all-linux-static
- all
- alldbg
- clang (manual)
- tci
- notcg (manual)
This is overkill. The main reason to run on these hosts is to get
coverage for the host architecture; we can leave the handling of
differences like debug vs non-debug to the x86 CI jobs.
The jobs are also generally running OK; they occasionally fail due to
timeouts, which is likely because we're overloading the machine by
asking it to run 4 CI jobs at once plus the ad-hoc CI.
Remove the 'allow_failure' tag from all these jobs, and switch the
s390x-alldbg, aarch64-all, s390x-tci and aarch64-tci jobs to manual.
(We keep -all on s390x and -alldbg on aarch64 just for diversity
of coverage.)
This will let us make the switch for s390x and aarch64 hosts from
the ad-hoc CI to gitlab.

If a chardev has a logfile the file is opened using
qemu_open_old() which does the job, but since @errp is not
propagated into qemu_open_internal() we lose much more accurate
error and just report "Unable to open logfile $errno". When
using plain files, it's probably okay as nothing complex is
happening behind the curtains. But the problem becomes more
prominent when passing an "/dev/fdset/XXX" path since much more
needs to be done.
The fix is to use qemu_create() which passes @errp further down.

Shield expansion connector. Mark the buses which are used only for
board-internal devices as 'full' so that if the user creates i2c
