* builtins.def (BUILT_IN_VA_ARG_PACK): New built-in.
* tree.h (CALL_EXPR_VA_ARG_PACK): Define.
* tree-inline.h (copy_body_data): Add call_expr field.
* tree-inline.c (expand_call_inline): Initialize call_expr.
(copy_bb): Append anonymous inline fn arguments to arguments
when inlining a CALL_EXPR_VA_ARG_PACK call.
* builtins.c (expand_builtin): Issue an error if
BUILT_IN_VA_ARG_PACK is seen during expand.
(fold_call_expr, fold_builtin_call_array): Don't fold
CALL_EXPR_VA_ARG_PACK CALL_EXPRs or calls with
__builtin_va_arg_pack () call as last argument.
* gimplify.c (gimplify_call_expr): If last argument to a vararg
function is __builtin_va_arg_pack (), decrease number of call
arguments and instead set CALL_EXPR_VA_ARG_PACK on the CALL_EXPR.
* expr.c (expand_expr_real_1): Issue an error if
CALL_EXPR_VA_ARG_PACK CALL_EXPR is seen during expand.
* tree-pretty-print.c (dump_generic_node): Handle printing
CALL_EXPR_VA_ARG_PACK bit on CALL_EXPRs.
