	* config/rs6000/rs6000-protos.h (get_data_alias_set): Rename
	get_TOC_alias_set for use with both TOC & pc-relative addressing.
	* config/rs6000/rs6000.c (create_TOC_reference): Add gcc_assert.
	(rs6000_legitimize_address): Add check for not pc-relative in TOC
	support.
	(rs6000_legitimize_tls_address_aix): Call get_data_alias_set
	instead of get_TOC_alias_set.
	(use_toc_relative_ref): Add check for SYMBOL_REF and not
	pc-relative to simplify callers.  Make tests easier to
	understand.
	(use_pc_relative_ref): New helper function.
	(rs6000_emit_move): Add basic support for pc-relative addressing.
	Call get_data_alias_set instead of get_TOC_alias_set.
	(data_alias_set): Rename static variable.
	(get_data_alias_set): Rename get_TOC_alias_set since it is now
	used for both TOC and pc-relative addressing.
	* config/rs6000/rs6000.md (cmp<mode>_internal2): Add support for
	pc-relative addressing.  Call get_data_alias_set instead of
	get_TOC_alias_set.
