Log message:
PR c/12913
* c-tree.h (struct c_label_list): Update comment.
(struct c_label_context): Rename to struct c_label_context_se.
(label_context_stack): Rename to label_context_stack_se.
(C_DECL_UNJUMPABLE_VM, C_DECL_UNDEFINABLE_VM, struct
c_label_context_vm, label_context_stack_vm, c_begin_vm_scope,
c_end_vm_scope): New.
(C_DECL_DECLARED_BUILTIN, C_DECL_USED): Use FUNCTION_DECL_CHECK.
* c-decl.c (pop_scope): Call c_end_vm_scope.
(pushdecl): Call c_begin_vm_scope for variably modified
declarations.

(label_context_stack_vm, c_begin_vm_scope, c_end_vm_scope): New.
(c_finish_goto_label): Check for jumping into scope of identifier
with variably modified type. Push label on stack for those jumped
to from current context of identifiers with variably modified
type.
(struct c_switch): Add blocked_vm.
(c_start_case): Initialize blocked_vm.
(do_case): Check blocked_vm.
(c_finish_case): Add comment.
(c_begin_stmt_expr, c_finish_stmt_expr): Update for renamed
variable label_context_stack.
objc:
* objc-act.c (objc_start_function): Create stack level for context
of identifiers with variably modified type.
testsuite:
* gcc.dg/c99-vla-jump-1.c, gcc.dg/c99-vla-jump-2.c,
