[patch] Move the default definitions of OUTGOING_REGNO andINCOMING_REGNO to defaults.h.

[Kazu Hirata <kazu at cs dot umass dot edu>]

Hi,

Attached is a patch to move the default definitions of OUTGOING_REGNO
and INCOMING_REGNO to defaults.h.

Bootstrapped on i686-pc-linux-gnu.  Committed as obvious.

	* alias.c (OUTGOING_REGNO): Don't define the default.
	* builtins.c (OUTGOING_REGNO): Likewise.
	(INCOMING_REGNO): Likewise.
	(apply_args_register_offset): Always use OUTGOING_REGNO.
	* combine.c (OUTGOING_REGNO): Likewise.
	* sibcall.c (OUTGOING_REGNO): Likewise.
	* defaults.h (INCOMING_REGNO): Provide the default.
	(OUTGOING_REGNO): Likewise.
