Port Helmut's trace/known-return to ppc.  Fix some bugs along the way
as well.

lisp/breakpoint.c:
o Enable function-end stuff in compute_offset for DARWIN too.
o Lots of printf's so we can see what's happening on ppc since gdb is
  majorly broken there.

lisp/ppc-assem.S:
o Actually implement the function-end breakpoint template.  Basically
  copied the sparc version, with appropriate mods.

lisp/ppc-arch.c:
o Add TWLLEI_R0 macro to create the appropriate trap instructions that
  we need, and use as appropriate.
o arch_install_breakpoint was actually broken and installed a twllgei
  instruction instead of twllei.
o arch_do_displaced_inst was also broken.  It didn't install the
  after-break-point trap after the breakpoint trap.  And it also
  didn't continue running the code and returned instead.  That's
  wrong.
o The trap_AfterBreakpoint case in sigill_handler was inserting the
  wrong instruction back.  (Probably too much copying of the sparc
  port.)

Implement tracing for the known-return convention.  This is basically
Helmut Eller's patch sent to cmucl-imp on 2005-03-08.  This basically
means tracing recursive functions will show all recursions during the
trace and not just the final call.

code/debug-int.lisp:
o Apply Helmut's patch.  Tweak it so when the known-return convention
  is being used, we tell MAKE-BOGUS-LRA that we're using the
  known-return so we can handle it properly.

lisp/breakpoint.c:
o Add an extra parameter to compute_offset so we know we're handling a
  function-end breakpoint or not.  Needed because reg_CODE isn't
  pointing to the bogus lra in this case, so the offsets are all
  wrong.  We compute the right offset for the known return and return
  the offset as negative so we can tell.
o Adjust all callers of compute_offset.
o Adjust handle_function_end_breakpoint to handle negative offsets
  from compute_offset so we can get the right code component for the
  bogus lra.

From Tim Moore; FreeBSD 4.x has new sigcontext code which can be accessed
via the POSIX_SIGS conditional. Change the way SA_SIGINFO gets passed
to sigaction. It is turned off for FreeBSD and Linux.

Fix recently introduced bugs in the breakpoint handling on non-x86
ports; fake_foreign_function_call must be called before sap_alloc on
the non-x86 port so that current_dynamic_space_free_pointer is setup
from reg_ALLOC.

For the x86 port store the return code component and the PC offset in
bogus LRA code objects rather than a SAP to avoid lossage if the real
code object is moved while the real return address has been moved off
the stack.

Breakpoint and single stepping support for the x86 port. This has been
