pointer-compare-1.c: Add __attribute__((used))

Browse Source 
c-c++-common/asan/pointer-compare-1.c assumes the certain order for
variable placement.  Add __attribute__((used)) to avoid variable
placement changes due to SHF_GNU_RETAIN.

	PR testsuite/97803
	* c-c++-common/asan/pointer-compare-1.c (global1): Add
	__attribute__((used))
	(global2): Likewise.
	(small_global): Likewise.
	(large_global): Likewise.
