Andrew Burgess c005eb9e34 ld: Extend options for altering orphan handling behaviour.

Replace the options --warn-orphan and --no-warn-orphan with a single
option --orphan-handling=MODE, where mode can be place, warn, error, and
discard.

Mode 'place' is the default, and is the current behaviour, placing the
orphan section into a suitable output section.

Mode 'warn' is the same as '--warn-orphan'.  The orphan is also placed
using the same algorithm as for 'place'.

Mode 'error' is the same as '--warn-orphan' and '--fatal-warnings'.

Mode 'discard' assigns all output sections to the /DISCARD/ section.

ld/ChangeLog:

	* ld.h (enum orphan_handling_enum): New.
	(ld_config_type): Remove warn_orphan, add orphan_handling.
	* ldemul.c (ldemul_place_orphan): Remove warning about orphan
	sections.
	* ldlang.c (ldlang_place_orphan): New function.
	(lang_place_orphans): Call ldlang_place_orphan.
	* ldlex.h (enum option_values): Remove OPTION_WARN_ORPHAN and
	OPTION_NO_WARN_ORPHAN, add OPTION_ORPHAN_HANDLING.
	* lexsup.c (ld_options): Remove 'warn-orphan' and
	'no-warn-orphan', add 'orphan-handling'.
	(parse_args): Remove handling for OPTION_WARN_ORPHAN and
	OPTION_NO_WARN_ORPHAN, add handling for OPTION_ORPHAN_HANDLING.
	* NEWS: Replace text about --warn-orphan with --orphan-handling.
	* ld.texinfo (Options): Remove --warn-orphan entry and add
	entry on --orphan-handling.
	(Orphan Sections): Add reference to relevant command line options.
