gcc/
	* bb-reorder.h (default_target_bb_reorder): Remove redundant GTY.
	* builtins.h (default_target_builtins): Likewise.
	* gcse.h (default_target_gcse): Likewise.
	* target-globals.h (target_globals): Add a destructor.  Convert
	void-pointer fields back to their real type and change from
	GTY((atomic)) to GTY((skip)).
	(restore_target_globals): Remove casts accordingly.
	* target-globals.c (save_target_globals): Use XCNEW rather than
	ggc_internal_cleared_alloc to allocate non-GC structures.
	Use ggc_cleared_alloc to allocate the target_globals structure
	itself.
	(target_globals::~target_globals): Define.
