from  Alexandre Oliva  <aoliva at redhat.com>

	PR debug/41276
	PR debug/41307
	* cselib.c (cselib_expand_value_rtx_cb): Document callback
	interface.
	(cselib_expand_value_rtx_1): Use callback for SUBREGs.  Adjust
	for VALUEs, to implement the documented interface.
	* var-tracking.c (vt_expand_loc_callback): Handle SUBREGs.
	Adjust for VALUEs and anything else, to implement the
	documented interface.
