Checkin the current code for gencgc. This is a basic port of sparc

gencgc for ppc.  This is not yet functional.  Allocation seems to
work, but GC does not.  We're just making a checkpoint now.

compiler/ppc/macros.lisp:
o Update allocation macro to support gencgc.  Need a temp-tn as a
  scratch register for inline allocation.
o Update with-fixed-allocation to use allocation macro correctly for
  gencgc.

assembly/ppc/array.lisp:
o Update for new allocation macro for gencgc.

code/ppc-vm.lisp:
o Define *scavenge-read-only-space*

compiler/ppc/alloc.lisp:
compiler/ppc/array.lisp:
compiler/ppc/call.lisp:
o Update to use new allocation macro for gencgc.

compiler/ppc/parms.lisp:
o Add necessary static symbols to support gencgc.

lisp/Config.ppc_darwin:
o Update to build with gencgc as needed.

lisp/Darwin-os.c:
o Update C code for gencgc.  Mostly for checking if pointer is in the
  dynamic space.
o Many debugging printf's enabled.

lisp/gencgc.c:
o Adjust sparc version appropriately for ppc.
o Enable many gencgc self-checks.

lisp/gencgc.h:
o Update PAGE_SIZE for ppc, which is 4K.

lisp/ppc-arch.c:
o Add necessary code to handle the allocation traps for gencgc.
  Basically ported sparc version for ppc.

lisp/ppc-assem.S:
o The way pseudo-atomic is done has been changed, so make the assembly
  code match.  PA is now more like sparc where the LSB is the
  PA-interrupted bit.
o do_pending_interrupt may need work.

lisp/ppc-validate.h:
o Make the READ_ONLY_SPACE_SIZE right.
o Define CONTROL_STACK_END.

lisp/purify.c:
o Enable debugging printfs
o Adjust purify for gencgc, basically copying sparc version.
