re PR target/26743 (gcc generates unreachable branch)

	PR target/26743
	PR target/11254
	PR target/10274
	* 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.
