	* libcoff-in.h (xcoff_tdata): Add a lineno_counts field.
	* libcoff.h: Regenerate.
	* xcofflink.c (xcoff_link_add_symbols): Record per-symbol
	line-number counts in the bfd's lineno_counts field.
	Don't keep per-csect line-number counts.
	(xcoff_sweep): Don't update per-csect line-number counts.
	(bfd_xcoff_size_dynamic_sections): Count the number of line-number
	entries in each output section.
	(xcoff_link_input_bfd): Get the number of line numbers from
	the bfd's lineno_counts field, rather than recalculating it
	from scratch.  Fix the range check when updating C_BINCL and
	C_EINCL symbols.
	(_bfd_xcoff_bfd_final_link): Don't count the output line numbers
	here.  Don't expect csects to have line-number counts.

ld/testsuite/
	* ld-powerpc/aix-lineno-1.s, ld-powerpc/aix-lineno-1.txt,
	ld-powerpc/aix-lineno-1a.dd, ld-powerpc/aix-lineno-1a.nd,
	ld-powerpc/aix-lineno-1b.dd, ld-powerpc/aix-lineno-1b.nd: New tests.
	* ld-powerpc/aix52.exp: Run them.  Copy aix-lineno-1.txt to tmpdir.
