cselib.c (LONG_TERM_PRESERVED_VALUE_P): Remove.

Browse source 
* cselib.c (LONG_TERM_PRESERVED_VALUE_P): Remove.
	(cselib_preserve_definitely, cselib_clear_preserve): Remove.
	(cselib_preserve_only_values): Remove retain argument, don't
	traverse hash table with cselib_{preserve_definitely,clear_preserve}.
	* cselib.h (cselib_preserve_only_values): Remove retain argument.
	* var-tracking.c (micro_operation): Move insn field before union.
	Add DEF_VEC_O and DEF_VEC_ALLOC_O for this type.
	(struct variable_tracking_info_def): Remove n_mos field, change
	mos into a vector of micro_operations.
	(count_uses, count_uses_1, count_stores, count_with_sets): Remove.
	(bb_stack_adjust_offset, log_op_type, add_uses, add_stores,
	compute_bb_dataflow, emit_notes_in_bb): Adjust for VTI (bb)->mos
	changing into a vector.
	(add_with_sets): Likewise.  Ensure MO_VAL_USE uops from add_stores
	come before all other uops generated by add_stores.
	(vt_add_function_parameters): Adjust for cselib_preserve_only_values
	argument removal.
	(vt_initialize): Likewise.  Adjust for VTI (bb)->mos changing into
	a vector.  Run just one pass over the bbs instead of separate counting
	and computation phase.
	(vt_finalize): Free VTI (bb)->mos vector instead of array.
