This patchseries does more of the conversion of the A64 decoder to
decodetree. It covers the exception-generation, system, load and
store instructions.
The rebasing of this on top of the atomics work turned out
hairy enough that I thought it was better to send this out
as a v2. There ae also a couple of new patches at the start
that fix minor things before we start moving the code around.
changes v1->v2:
* patch 2 is new (but already sent separately and reviewed)
* patches 3 and 4 are new (fixes to recent refactoring)
* patch 14 (ld/st pair) is structurally the same as the old
patch 11, but the underlying code changed enough in the
atomics work that I figured it was worth getting it
re-reviewed.
* The very cautious might also want to re-check some of
the other load/store patches, but the changes there were
rather less, so I have retained the R-by tags
* patch 22 (ld/st single struct) decode reworked to follow
RTH's suggestion
Patches needing review: 3, 4, 14, 22
thanks
