Subject: make LABEL_REF_LABEL a rtx_insn *

While changing LABEL_REF_LABEL it might as well become an inline
function, so that its clearer what types are involved.  Unfortunately
because it is still possible to use XEXP and related macros on a
LABEL_REF rtx you can still set the field to be a non insn rtx.  The
other unfortunate thing is that the generators actually create LABEL_REF
rtx that refer to MATCH_x rtx, so there we actually need to use XEXP to
bypass the checking this patch adds.
