Remove arm support for IPKDB.

It hasn't worked since arm was broken out from arm32 in Jan 2001, and
no-one has noticed or cared to fix it.

Overhaul arm32's abort handlers:

 - Assume a permission fault is always the result of an attempted
   write, so no need to disassemble the opcode.
   (as discussed with Richard Earnshaw/Jason Thorpe a week or two ago)

 - Split out non-MMU data aborts into separate functions, and deal
   correctly with XScale imprecise aborts. Specifically, the old code
   made no attempt to handle the double abort faults which can occur
   as a result of two consecutive external (imprecise) aborts. This
   was easy to provoke by read(2)ing from a /dev/mem offset which caused
   an external abort. With the old code, this would bring the system
   down instantly, with little clue as to why. (hint: tf_spsr held
   PSR_ABT32_MODE...)

 - Re-write badaddr_read() to use pcb_onfault instead of adding extra
   overhead to data_abort_handler(). A side effect of this is that it
   now benefits from the XScale double abort recovery.

 - Invoke the cpu-specific prefetch/data abort fixup routines only if
   the host cpu actually needs it. On other cpus, the code is optimised
   away.

 - Sprinkle __predict_{false,true} in all the right places.

 - G/C some excess debugging baggage.

Move the alignment fault enable/disable code into macroes to avoid
needless duplication.

Additionally, merge AST handling into the same code.

exception.S and the generic irq_dispatch.S routines have been updated
to use the macroes.

XXX: I have patches for the non-generic IRQ dispatch routines, but they
need testing by someone with hardware.

Enable alignment faults on arm32 for both kernel and userland.

If COMPAT_15 and EXEC_AOUT are defined, support per-process
alignment checking where AFLTs are always enabled when running
kernel code and userland ELF binaries, and dynamically disabled/
enabled when switching to/from a.out binaries. This is necessary
in order to execute older a.out binaries, where gcc made
deliberate use of misaligned loads under certain circumstances.

Instead of "add rd, pc, #foo - . - 8", use either "adr rd, foo" or (where
