* system.h: Forward-declare struct rtx_def, struct rtvec_def,
and union tree_node. Typedef rtx, rtvec, and tree. Fix comment.
* rtl.h: Don't forward-declare union tree_node here. Don't
typedef rtx or rtvec here. Change all uses of struct rtx_def *,
struct rtvec_def *, or union tree_node * to use rtx, rtvec,
and tree respectively.
* tree.h: Don't forward-declare struct rtx_def here. Don't
typedef tree here. Change all uses of struct rtx_def *,
struct rtvec_def *, or union tree_node * to use rtx, rtvec,
and tree respectively.
