	of int if __SIZEOF_INT__ == 2.
	* c-c++-common/Wrestrict.c: Test memcpy range with smaller length when
	__SIZEOF_SIZE_T < 4.
	* c-c++-common/rotate-8.c: Define smaller "large" constant when
	__SIZEOF_INT__ == 2.
	* gcc.dg/pr53037-1.c: Add dg-require-effective-target int32.
	* gcc.dg/pr53037-2.c: Likewise.
	* gcc.dg/pr53037-3.c: Likewise.
	* gcc.dg/pr85512.c: Likewise.
	* gcc.dg/pr59963-2.c: Add dg-warning for int16.
	* gcc.dg/sancov/cmp0.c: Explicitly use __INT32_TYPE__ instead of int.
	* gcc.dg/tree-ssa/addadd.c: Fix dg-final directives for int16.
	* gcc.dg/tree-ssa/pr79327-2.c: Likewise.
	* gcc.dg/tree-ssa/builtin-sprintf-2.c: Filter out invalid tests for
	int16.
	* gcc.dg/tree-ssa/builtin-sprintf-warn-10.c: Update sizes in dg-warning
	directives for int16.
