Process max 4k bytes at a time, writing back registers between the
accesses. The instruction is interruptible.
"For operands longer than 2K bytes, access exceptions are not
recognized for locations more than 2K bytes beyond the current location
being processed."
Note that on z/Architecture, 2k vs. 4k access cannot get differentiated as
long as pages are not crossed. This seems to be a leftover from ESA/390.
Simply stay within single pages.
MVCL handling is quite different than MVCLE/MVCLU handling, so split up
the handlers.
Defer interrupt handling, as that will require more thought, add a TODO
for that.
