	* src/atomic_ops/sysdeps/gcc/arm.h (AO_THUMB_GO_ARM,
	AO_THUMB_RESTORE_MODE, AO_THUMB_SWITCH_CLOBBERS): Define new
	macro (to switch temporarily CPU mode to ARM in inline assembler
	if compiling in the Thumb mode and to restore it back on leave).

	AO_test_and_set, AO_fetch_and_add, AO_fetch_and_add1,
	AO_fetch_and_sub1, AO_compare_and_swap, AO_test_and_set_full):
	Enable compilation in the Thumb mode (use AO_THUMB_GO_ARM,
	AO_THUMB_RESTORE_MODE and AO_THUMB_SWITCH_CLOBBERS macros).
	* src/atomic_ops/sysdeps/gcc/arm.h (AO_store, AO_test_and_set,
