This adds KVM's syz_kvm_setup_cpu pseudo syscall. This adds placeholder
for options (none implemented yet).
This adds instruction generator for ifuzz; this also adds a few pseudo
instructions to simulate super/hyper/ultracalls
(a PPC64/pseries platform thing).
The insns.go is generated from PowerISA_public.v3.0B.pdf [1] by
a horrendous python3 script on top of pdftotext. The ISA covers POWER9
which is the latest available POWER CPU at the moment. The next ISA
for POWER10 is quite different and we will deal with it later.
The // comment after every instruction is a fixed opcode list for
verification purposes.
This does not define DecodeExt as there is no obvious replacement of
the Intel XED library for POWERPC (gapstone-capstone, later, may be).

This fixes an error in printf() format for __u64:

Move the test from pkg/csource to executor/
in order to be able to (1) run it on *.cc files,
(2) run on unprocessed *.h files, (3) produce line numbers.
Add a check for missed space after //.

Make as much code as possible shared between all OSes.
In particular main is now common across all OSes.
Make more code shared between executor and csource
(in particular, loop function and threaded execution logic).
Also make loop and threaded logic shared across all OSes.
Make more posix/unix code shared across OSes
(e.g. signal handling, pthread creation, etc).
Plus other changes along similar lines.
Also support test OS in executor (based on portable posix)
and add 4 arches that cover all execution modes
(fork server/no fork server, shmem/no shmem).
This change paves way for testing of executor code
and allows to preserve consistency across OSes and executor/csource.
