konstantinos was only able to do this *after* i had created the
test_caller_svp64_chacha20.py unit test.

in ISACaller you can pre-load *and extract* all regs in python
which is far far easier.

go *slow*, maximum of 5-8 lines of assembler at a time, and bootstrap
your way up.

then once the snippets are ready in test_caller_xxxx.py you are
ready to move to pypowersim.  you will need to do a *full* function
as a ".s" file just like how konstantinos did it, starting from:

* a POWER v3.0 c function compiled to assembler with gcc -S
* dropping that into the test binary *in place* of the c file
* converting line by line to svp64 assembler, taking the fragments
  from the *python* unit test and dropping them in.

all of this is slow patient and above all *incremental* work that you
can in no way shortcut or attempt to just go "i will do everything from
cold".
