Merge code from main branch of 2005-12-17 to ppc gencgc branch.  Still
doesn't work of course.

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.

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

o Update for new allocation macro for gencgc.

o Define *scavenge-read-only-space*

o Update to use new allocation macro for gencgc.

o Add necessary static symbols to support gencgc.

o Update to build with gencgc as needed.

o Update C code for gencgc.  Mostly for checking if pointer is in the
  dynamic space.
o Many debugging printf's enabled.

o Adjust sparc version appropriately for ppc.
o Enable many gencgc self-checks.

o Update PAGE_SIZE for ppc, which is 4K.

o Add necessary code to handle the allocation traps for gencgc.
  Basically ported sparc version for ppc.

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.

o Make the READ_ONLY_SPACE_SIZE right.

o Enable debugging printfs
o Adjust purify for gencgc, basically copying sparc version.

Change how pseudo-atomic works on Mac OS X.  Instead of using a
separate register for the flag, and using a negative alloc-tn to mean
the pseudo-atomic section was interrupted, we make it more like sparc,
where the pseudo-atomic interrupted is the least signficant bit of

* compiler/ppc/macros.lisp:
  o Make the PSEUDO-ATOMIC macro work as desired.

* lisp/ppc-arch.c
  o Set the LSB of alloc-tn when pseudo-atomic is interrupted.
  o Check for the twnei instruction which is now used to see if
    pseudo-atomic was interrupted.

* lisp/ppc/assem.S
  o Use the new pseudo-atomic scheme.

Save FP register args before calling lazy_resolve_linkage.  (Might not
be necessary, but this is safe.)

Initial support for linkage-tables on PPC/Darwin.  This is a
relatively straightforward port of the sparc version of
linkage-tables.  Some refinements are probably still needed, as well
as some testing.

Use boot-2005-02-ppc-linkage.lisp to bootstrap this change from the
2005-02 snapshot.

* code/ppc-vm.lisp
    functions for linkage-table.

* compiler/generic/new-genesis.lisp
  o Basically do the same as the sparc port for linkage-tables.
  o need to extern-alien-name on the cold linkages since they C names
    depend on the backend conventions.

* compiler/ppc/alloc.lisp
  o Load "undefined_tramp" appropriately for linkage-tables.

* compiler/ppc/c-call.lisp
    FOREIGN-SYMBOL-DATA-ADDRESS) for linkage-tables so we can access

* compiler/ppc/cell.lisp
  o Load "closure_tramp" appropriately for linkage-tables
  o Load "undefined_tramp" appropriately for linkage-tables

* compiler/ppc/parms.lisp
  o Put the foreign linkage space start at the end of the static space
    to make it easier to bootstrap.  (We need already mapped memory.)
    We can move this later.
  o Add new static-symbol *linkage-table-data*
  o While were at it, add SPARE-9 and SPARE-0 static symbols so we
    have 10 spares.

* lisp/Config.ppc_darwin
  o Add -DLINKAGE_TABLE to CFLAGS/ASFLAGS if we have linkage-table

* lisp/Darwin-os.c
  o Add os_dlsym to support linkage-tables.  (This nees a little
    refactoring because we just copied the #defines for dlopen modes.)

* lisp/os-common.c
  o The checking of the linkage tables that is done for sparc almost
    works for ppc, but not quite.  Implement one for ppc.

* lisp/ppc-arch.c
  o Add PPC version of arch_make_jump_entry, arch_make_linkage_entry,

* lisp/ppc-assem.S
  o Add lazy_resolve_linkage to support linkage-tables.  This needs
    some more work.
  o Add undefined_foreign_symbol_trap.  This probably needs work, and
    definitely needs testing.

* lisp/ppc-validate.h
  o Define the start of the linkage space and size.

lispregs.h, sparc-lispregs.h:
  o Move the SC_OFFSET_{HI,LO} macros from sparc-lispregs to
    lispregs.h, so they can be used elsewhere.

  o Define the register numbers so they can be used in the SC_OFFSET

  o Document what the byte 18<<2, 0, 0, 24 is supposed to do.
  o Use the SC_OFFSET macros in undefined_tramp instead of hard-wiring
    the register number.

(defun foo () (zot)) when compiled and run gave a silly message about
#C(0d0 0d0) failing a typecase.  Then doing a backtrace gave another
error about some negative number not being a positive fixnum.

The former error is caused by a bad definition of undefined_tramp.
The latter error is caused by the debugger not being able to compute
the offset correctly.

(Fixes ported from sbcl.)

First merge of the C side of the OS X/Darwin port.  Besides adding Darwin
versions of all the required things, this commit separates the
interrupt handler proper (now interrupt_handle_now_handler) from the
actual work-horse (interrupt_handle_now), which is now only ever called
from the two interrupt handlers, interrupt_handle_now_handler and
maybe_now_maybe_later.  This follows similar changes in SBCL, and is in
fact needed in order to properly use sigreturn in signal handlers, as
required to work around a problem with the G5.
