* config/tc-ia64.c (unwind): Add prologue_mask member.

Browse source 
(dot_vframe): Elide psp_gr record if it overlaps prologue_gr.
        (dot_save): Likewise for pfs_gr, rp_gr, and preds_gr.
        (dot_body): Clear unwind.prologue_mask.
        (dot_prologue): Set it.  Accept a register second argument.
