PR libgomp/90641
	* work.c (gomp_init_work_share): Instead of aligning final ordered
	value to multiples of long long alignment, align to that the
	first part (ordered team ids) and if inline_ordered_team_ids
	is not on a long long alignment boundary within the structure,
	use __alignof__ (long long) - 1 pad size always.
	* loop.c (GOMP_loop_start): Fix *mem computation if
	inline_ordered_team_ids is not aligned on long long alignment boundary
	within the structure.
	* loop-ull.c (GOMP_loop_ull_start): Likewise.
	* sections.c (GOMP_sections2_start): Likewise.
