        * pa.md (cbranch patterns): Revise arguments used in calls to
        output_cbranch, output_bb and output_bvd.  Add long branch length
        attributes.
        (fbranch patterns): Handle long branches.
        (jump): Revise length check.  Revise arguments for output_lbranch call.
        Add long branch length attributes.
        (decrement_and_branch_until_zero): Add long branch length attributes.
        (output_movb, output_parallel_addb and output_parallel_movb patterns):
        Likewise.  Revise arguments for output_parallel_addb and
        output_parallel_movb calls.
        * pa-protos.h (output_cbranch, output_lbranch, output_bb, output_bvb,
        output_parallel_movb and output_parallel_addb): Update prototypes.
        * pa.c (output_cbranch): Revise arguments.  Correct handling of
        nullification in long branches.
        (output_lbranch): Add new argument to control extraction of delay
        instruction.
        (output_bb): Handle long branches.
        (output_bvb, output_dbra, output_movb, output_parallel_movb,
        output_parallel_addb): Likewise.
