testsuite/52641: Fix sloppy tests that did not care for sizeof(int)=2 etc.

gcc/testsuite/
	PR testsuite/52641
	* gcc.c-torture/compile/attr-complex-method-2.c [target=avr]: Check
	for "divsc3" as double = float per default.
	* gcc.c-torture/compile/pr106537-1.c: Use __INTPTR_TYPE__ instead of
	hard-coded "long".
	* gcc.c-torture/compile/pr106537-2.c: Same.
	* gcc.c-torture/compile/pr106537-3.c: Same.
	* gcc.c-torture/execute/20230630-3.c: Use __INT32_TYPE__ for bit-field
	wider than 16 bits.
	* gcc.c-torture/execute/20230630-4.c: Same.
	* gcc.c-torture/execute/pr109938.c: Require int32plus.
	* gcc.c-torture/execute/pr109986.c: Same.
	* gcc.dg/fold-ior-4.c: Same.
	* gcc.dg/fold-ior-5.c: Same
	* gcc.dg/fold-parity-5.c: Same.
	* gcc.dg/fold-popcount-5.c: Same.
	* gcc.dg/builtin-bswap-13.c [sizeof(int) < 4]: Use __INT32_TYPE__
	instead of int.
	* gcc.dg/builtin-bswap-14.c: Use __INT32_TYPE__ instead of int where
	required by code.
	* gcc.dg/c23-constexpr-9.c: Require large_double.
	* gcc.dg/c23-nullptr-1.c [target=avr]: xfail.
	* gcc.dg/loop-unswitch-10.c: Require size32plus.
	* gcc.dg/loop-unswitch-14.c: Same.
	* gcc.dg/loop-unswitch-11.c: Require int32.
	* gcc.dg/pr101836.c: Use __SIZEOF_INT instead of hard-coded 4.
	* gcc.dg/pr101836_1.c: Same.
	* gcc.dg/pr101836_2.c: Same.
	* gcc.dg/pr101836_3.c: Same.
