This is mostly code movement at this point, out of headers
and into op_helper.c and debug_helper.c.  I have dropped all
the bits that change where route_to_el2 is computed -- it
remains in raise_exception alone.

The last patch has the tiniest of bug fixes, which probably
isn't even visible, because we don't ask for fp_exception_el
with el != current without SVE.
