I think something got lost here... anyway, I just checked that these functions
and they're only used in spr_tcg.c.inc at this point, so I think I'll remove it
from the .h and make them static. And mention it in the commit message
as well
I could also put it in translate.c, but whoever needs to refactor this code next
would have as big a headache as we're having now.

The 2 fscr functions below aren't readers and writers for the FSCR.
Instead they're used by instructions related to facilities the FSCR
can enable and disable - this generates the code to check the FSCR and
generate an exception if the units are disabled.
That doesn't mean they don't belong here, but it does mean

Sure, I can separate it like this. It was just easier to make the commit like this, since
I wouldn't need to undo all the static removals and redo them for the next commit
(I tend to work through all the code and then separate changes into commits, maybe
that's a bad habit I should drop), and also I thought it would making reviewing the
next patch easier.

Oops, another one that I forgot. This has the same issue as the one before, so I'm
guessing the same solution: move the define to internal, so both cpu_init.c and
translate.c can access it.

Good catch again. But my question (in the comment at the begining) remains:
Is there a good reason to keep them separate from spr_(read|write)_xer, since
they are only used by those functions and aren't much different than other
read|write functions.

Yeah... I didn't know about the automated sed command until earlier today
so it didn't occur to me that it could be a problem. The rearranging was either
an accident, or a way to reduce ifdefs, but that can be a trivial patch later on

the define was moved to internal.h (forgot to include in this patch, it's in the
next one, will fix). I don't know if that's a good solution, but it's working for now

Same as before: They were added to internal.h and I forgot.

Moved all functions related to SPR read/write callbacks into a new file
specific for holding these. This is setting up a better separation of
SPR registration, which is required to be able to build disabling
TCG.
The solution to move it to spr_tcg.c.inc and including it in translate.c
is a work in progress, any better solutions are very much appreciated.
Also, making the R/W functions not static is required for the next
commit.
