* function.c (nonlocal_goto_handler_slots): Renamed from
nonlocal_goto_handler_slot; now an EXPR_LIST chain.
(push_function_context_to): Adjust for this change.
(pop_function_context_from): Likewise.
(init_function_start): Likewise.
(expand_function_end): Likewise.
* function.h (struct function): Likewise.
* calls.c (expand_call): Likewise.
* explow.c (allocate_dynamic_stack_space): Likewise.
* expr.h (nonlocal_goto_handler_slots): Rename its declaration.
* stmt.c (declare_nonlocal_label): Make a new handler slot for each
label.
(expand_goto): When doing a nonlocal goto, find corresponding handler
slot for it. Don't put the label address in the static chain register.
(expand_end_bindings): Break out nonlocal goto handling code into
three new functions.
(expand_nl_handler_label, expand_nl_goto_receiver,
expand_nl_goto_receivers): New static functions, broken out of
expand_end_bindings and adapted to create one handler per nonlocal
label.
* function.c (delete_handlers): Delete insn if it references any of
the nonlocal goto handler slots.
* i960.md (nonlocal_goto): Comment out code that modifies
static_chain_rtx.
* sparc.md (nonlocal_goto): Likewise.
(goto_handler_and_restore_v9): Comment out.
(goto_handler_and_restore_v9_sp64): Comment out.
