2014-08-19  David Malcolm  <dmalcolm@redhat.com>

	* sched-int.h (DEP_PRO): struct _dep's "pro" and "con" fields will
	eventually be rtx_insn *, but to help with transition, for now,
	convert from an access macro into a pair of functions: DEP_PRO
	returning an rtx_insn * and...
	(SET_DEP_PRO): New function, for use where DEP_PRO is used as an
	lvalue, returning an rtx&.
	(DEP_CON): Analogous changes to DEP_PRO above.
	(SET_DEP_CON): Likewise.

	* haifa-sched.c (create_check_block_twin): Replace DEP_CON used as
	an lvalue to SET_DEP_CON.
	* sched-deps.c (init_dep_1): Likewise for DEP_PRO and DEP_CON.
	(sd_copy_back_deps): Likewise for DEP_CON.
	(DEP_PRO): New function, adding a checked cast for now.
	(DEP_CON): Likewise.
	(SET_DEP_PRO): New function.
	(SET_DEP_CON): Likewise.
