f84ce5442e Refactor handling of auxiliary stacks and setjmp/longjmp 
* libguile/__scm.h (scm_i_jmp_buf): Remove definition, which was a shim
  for ia64.  Instead, always use setjmp/longjmp and jmp_buf.
* libguile/_scm.h (SCM_I_SETJMP, SCM_I_LONGJMP): Remove; instead use
  setjmp and longjmp.
* libguile/continuations.c (capture_auxiliary_stack):
  (restore_auxiliary_stack): New helpers.
  (scm_i_make_continuation): Use capture_auxiliary_stack.
  (copy_stack_and_call): Use restore_auxiliary_stack.  No need to stash
  the aux stack on the thread, either.
* libguile/continuations.h (scm_t_contregs): Use
  SCM_HAVE_AUXILIARY_STACK to flag when to have an auxiliary_stack
  member.
* libguile/control.h:
* libguile/control.c (reify_partial_continuation, scm_c_abort):
  (scm_suspendable_continuation_p): Adapt to use setjmp/longjmp
  directly.
* libguile/deprecated.h: Add deprecated scm_i_jmp_buf define.
* libguile/dynstack.h:
* libguile/dynstack.c (PROMPT_JMPBUF):
  (scm_dynstack_push_prompt, scm_dynstack_find_prompt):
  (scm_dynstack_wind_prompt): Adapt to jmp_buf type.
* libguile/eval.c (eval): Use jmp_buf and setjmp directly.
* libguile/gc-malloc.c: No need for ia64-specific things.
* libguile/gc.c: No need for ia64-specific things.
* libguile/gc.h: No need to declare scm_ia64_ar_bsp.
* libguile/init.c: Remove typedef of setjmp_type for Cray, unused.
* libguile/threads.c (guilify_self_1): No more pending_rbs_continuation
  in scm_i_thread, and register_backing_store_base is handled by libgc.
  (scm_ia64_ar_bsp): Remove definitions; inlined into continuations.c's
  capture_auxiliary_stack.
* libguile/threads.h (scm_i_thread): jmpbuf member is plain jmp_buf.
* libguile/throw.c (catch): Just use jmp_buf and setjmp.
* libguile/vm-engine.c (VM_NAME): Adapt prototype to take jmp_buf
  pointer.
* libguile/vm.c (vm_abort): Adapt jmp_buf types.
  (scm_call_n): Use setjmp.

13cafca168 Add raw u8-ref, etc instructions 
* libguile/vm-engine.c (PTR_REF, PTR_SET): New helper macros.
  (u8-ref, u16-ref, u32-ref, u64-ref, s8-ref, s16-ref, s32-ref, s64-ref)
  (u8-set!, u16-set!, u32-set!, u64-set!, s8-set!, s16-set!, s32-set!, s64-set!)
  (f32-ref, f64-ref, f32-set!, f64-set!): New instructions.
* module/system/vm/assembler.scm:
* module/language/cps/compile-bytecode.scm (compile-function):
* module/language/cps/slot-allocation.scm (compute-var-representations):
* module/language/cps/types.scm: Add optimizer and backend support for
  the new instructions.

9222e4df4b Add support for raw gc-managed pointer locals 
* libguile/vm-engine.c (gc-pointer-ref/immediate)
  (gc-pointer-set!/immediate): New instructions.
  (SP_REF_PTR, SP_SET_PTR): New helper definitions.
* libguile/vm.c (SLOT_DESC_LIVE_GC): Rename from SLOT_DESC_LIVE_SCM, as
  it can indicate GC-protected raw pointers also.
  (scm_i_vm_mark_stack): Adapt.
* module/system/vm/assembler.scm (write-arities):
* module/system/vm/debug.scm (arity-definitions): Add gcptr
  representation.  This is a binary-incompatible change!
